iOS 4 Upgrade Issues Reported by iPhone Users - Tell Us Your Upgrade Story [Updated]

I had a good experience update my 3Gs 16GB. I had backed it up the day before, put it on airplane mode so that a call or text wouldn't disrupt the process and all in all it took about 15minutes.

I experienced an issue with fuzzy pictures that had been synced in albums from my mac but I hooked up to itunes again last night and after syncing, pictures have returned to normal :)

I'm a happy girl but now need to decide if I'm hitting the o2 shop in the morning to get the new gadget :S

I upgraded to 4.0, my phone is now very slow. The pictures were blurry but after syncing with itunes it sorted them out. Even maps takes forever, everything takes at least 5-10 times longer than what it used to.. Come on Apple, sort out the issues and get a new update asap!!!

Yep, 3G upgraded and things seem to be slower now.

I have the same slowness problem after upgrading my 3G to IOS4. Upgrade went fine. But everything is slow. very frustrating. Especially notice it in Maps and accessing my contacts, and typing. I would like to roll back to v3.13, anyone know how?

Upgrade went ok for my 3GS however I have lost all my contacts. They are backed up in my gmail account however I have been unable to sync with it. Recreating the Exchange account has not helped.

Upgrade on 3GS went flawlessly from iTunes 9.2 and the backup I had for my GS. All store apps and contacts came across fine.

I have had major issues a well, backed up iPhone 3G, upgraded to Ver 4, went to restore from backup and all apps gone, contacts gone, notes gone, not happy. Had a years worth of notes and voice memos and ideas.

yes me too, any idea how to get them back

I have had the same issue, with a great many important and carefully labeled music and voice ideas as well as business mentoring sesions etc. All the data has been saved in my Itunes but does not appear on the iphone with my custom labels so I have no idea what any of the items are.
big disappointment with the speed opening apps like camera etc too. I wish I had never upgraded at the moment

I've tried several times to update a family member's 3G with no luck. I do a normal iTunes backup, succesful, then start the upgrade, it insists on its own backup, gets about 15 minutes in and locks up - same in 3 tries. After reading several articles about this I think we will skip the upgrade for the 3G, since some complain of data loss and complete ruination.

I successfully updatd my own 3Gs, although I do think the pictures (pre-upgrade, and newly taken) look slightly blurry, so I emailed one and its fine on my pc. I suspect they modified the viewer so its optimal to a v4, higher resolution display, and so I'll have to live with that. Hopefully they'll patch it for us 3G/3Gs owners - showing a friend a pic on my iPhone now doesn't make the iPhone look so good now does it?

Yup same here - 3G upgrade to OS4 - backs up fine in iTunes but the OS4 upgrade backup just freezes its been going a couple of hours now and still at the 5% stage. Guess I'll cancel it.

Given some of the contact issues listed everywhere think I'll wait - probably a bug fix version in the works. Android anyone?

I hate to admit it after all the hipe about iOS4 installations going wrong, I was hesitant. Installed today on 3Gs. It was done within 15 minutes without any problems. Pictures look blurry after install. Synched with iTunes which optimized all pictures on the phone, now they are crystal clear again. I am loving iOS4!!

download, unpack, install, reboot: everything without any problem on a ipod-touch 2nd generation

iOS4 on my 3rd gen iPod touch went fine. Intact I'm on it now.

No problems whatsoever upgrading iPhone 3G to IOS4. Took a bit longer than normal but worked just as it should!

The upgrade of my 3gs went flawlessley and was quite quick. However I did a full reboot of my iPhone afterwards just to make sure that everything had settled down.

Upgrade went perfectly. I have a 3GS and this was the first time I tried something like this. Sorry to hear other are having issues. I love the multitasking program. The battery seems to last just as long as it did before.
No complaints from me.

I installed the version 4 update on the 3G. It seemed all went well. When the installation completed my notes,apps. and telephone contacts were missing. Is there a way to locate and recover the files on my iMac v. 10xx?

PS:I attempted the install at least 4 times with the same results.

upgrade to my 32GB 3Gs went smooth but battery life is greatly reduced. Prior to upgrade I could make it through most days (~12 hours) of moderate use and now I'm discharging in 3-4 hours even with light use.

My battery on the 3GS went from 100% fully charged, down to 46% right after a 11 Minutes on the phone and I lost my contacts. Wish there was an option to turn off muti-tasking in a future software update.

Upgraded ny iPhone 3G running 3.1.3 to ios 4 using apple recommended procedure (connect to iTunes and click check for update).

Took more than 75 minutes (have 100+ applications).

The following issues were encountered:
1. I have a new category "other" of size 1.14GB on my iPhone???
2. When sending text messages - there is no running count x/160?
3. wall paper has only one setting?

Cheers

Tried to update iPhone 3G 16Gb and iTunes backup is hanging like a wet shirt on a rainy day!

I have a 3GS and the update stalled and the phone won't work. How can I get the phone to work?

After upgrading my 3G phone over the various updates, I was assuming that all would be well with the latest version 4 upgrade. How wrong I was!

I lost all my contacts, and many of the General settings such as setting up a simple 4 figure password do not work, and another facility such as changing the length of time the screen stays active. I usually set it from the default 1 minute to 'do not set' but this does not work either.

I've lost all my email history, addresses, as well as text message history, and Calendar settings and dates, appointments etc.

Very disappointed.

Paul Y

Same issues here too. Also rearranged all my apps and removed the password login and lost most contacts

Tried several times but it hangs in the backup process. So no luck. It is helpful to hear from others that it should only take 15 minutes ...

Apple is losing its touch. Too much hype so people go crazy anticipating and spendind money they don't have to upgrade to a phone they do not need. Where is apple's take on all this? As always, Steve is silent.

I'm on day two of trying to upgrade my Gen2 iPod Touch. The upgrade has been running for 12 hours trying to "backup" the device. The first time, I canceled the upgrade because it wasn't responding. Afterward, the device was very slow to respond to simple commands, and the few things I tested had problems, like email could no longer connect to my Gmail account. I did a reboot, and it took about 15 minutes. Now, I'm trying the upgrade again, but after 12 hours the status bar is at only about 10%, so I guess I will have to abort? Or do I let it run for days? It is working my computer very hard, but doesn't seem to have anything to show for it. This may or may not be associated with the fact that I had an Apple syncnotifier error message for the last couple of months that I finally fixed by uninstalling and reinstalling everything Apple on my computer, including iTunes. Just don't know what to do now. I have a PC, so maybe I should have just stuck with a PC-friendly company.

iPhone 3G fails at backup four times. After reading the pages of problems others have also I'm going to skip this update. It's not worth the risk of forcing the update, crashing the hell of something very important and panicking. It doesn't 'work' like it should so I'll wait.

I have a Macbook Pro running Mac OS X 10.6.4, iTunes 9.2. I upgraded my iPhone 3G from 3.1.3 to iOS4 with NO problems.

My upgrade to iOS4 on my iPhone 3GS seemed to go off without a hitch - until I tried to play music via the iPod app. The iPod app shuts down within 3 seconds every time I launch it. Everything else seems to be working well, but all the new bells and whistles are not worth giving up all the media functions.

3GS - upgrade apparently fine for the first few days, so generally really pleased. Folders, tick. Multitasking, qualified tick, but mostly because the things I'd need it for already have it from Apple (e.g. email). But on day 4 I wanted to use the Maps app, and it showed my the normal map view just fine. Right up until I wanted the Satellite view, at which point I lost everything. Oh, except the blue dot showing where I am. Cool, I'm on a grey page or a grey page with grid.

So, Apple needs to sort this quickly before my speed camera detector fails and I have to claim back my tickets...

My 3GS was a Bitch!!! When I connected to ITunes on my MAC, it said a new version was available, OK, It downloaded the new firmware from Apple then proceeded to install. Just after the progress bar got below the Apple symbol it froze there. It would not move for 30 mins. I disconnected the Iphone it went into recovery mode. It would not reload 3.1.3 as Apple would not allow it. Tried ios 4.0 5 times, recovery mode, DFU mode , same thing, nothing worked. Booted VMWare and connected to Windows ITunes, I got it to reload 3.1.3 by redirecting the Apple verification server. Plugged it into my MAC ITunes again, Fail again. Finally got the download onto my Windows ITunes and loaded from there no issues!!!

A PC comes to the rescue, so much for easy install, this has been the worst, I have has an IPhone since the 2G came out, this was defiantly the worst upgrade.

Just upgraded my 16GB 3G to ios4. Upgrade took a little longer than I would have liked (I only had around 400MB of space left) but it worked fine on the first "try".

I've restored every single iPhone I ever touch. Never had any problem accept setting tmobile MMS. The settings would erase them selfs but that wads bug there since the beginning. My frist restore on a 3GS I lost data service to the phone. But that was because I used UPDATE. Just to try it out since apple said it was easy. Yeah right. Any that was all on a Mac. I took my custom firm to a win7pc and restored it. I brought it back to Mac to restore from backup. All went find. Does anyone else still see the YouTube icon when in the multitasking window? Just wondering. Pc and Mac upto date and tune 9.2

I upgraded to IOS4 on my 3GS to-day. I did a backup first with itune. Upgraded my 3GS , the upgrade process went smoothly, took about 20mins. My phone started up All my contacts and notess were intact. I had confirmed that I was running V.4 and the About, showed V.4 on my phone.However, when I tried the multi task feature, I could not multi task any of the iphone apps or third party apps.

I like many had no problems with updating in the past. I even enjoyed the days off an update just to get to grips with new features. This experience has been abolished with the IOS4. I’ve had my 3G for just over a year (just). I came to update to the IOS4. The update took a long time but I got there in the end. However when iTunes sync came into play is where Im having problems my apps moved across no problems but then I got iTunes couldn’t back up my iPhone because the computer wouldn’t allow. I googled this and came to apples support guide on the matter. which was just delete the back up file in preferences (before I did this I did get a text from someone I know but his name wasn’t coming up just the number I feared then Id lost my contacts) so I did delete my back up. but then the next problem was iTunes couldn’t backup because of an unknown error (-20) (I’ve researched this unknown error and I can’t find anything on it) so I restored the software on iTunes and still I get this error so now Im left with a iPhone with no music, no contacts, no saved app data even apps crash on start. To simply buy an iPhone 4 is not an option I bought my phone outright on a payandgo and Im disgusted that an apple employee can even suggest that. now that I know Im not alone on this I want to know just what apple are going to do to fix this asap (for the money I paid I could off got a decent laptop with Skype) I expect and demand a resolution to my problem that isn’t going to cost me more time and money than it already has.

Since I downloaded the ios 4, I've been having problems with the notes app. I would type information such as a time and what I was doing. I would close the notes app and then go back in and all the information I typed is GONE! I try to take a picture of it because sometimes I have to type the information in three times! I tried looking online to see if anyone else has had this problem but I did not see any forums regarding the notes app.

same EXACT problem. It's the craziest thing I've seen on an iPhone, it saves then the time changes and all text recently typed vanishes.

Im having the same problem. I write a lot of notes and one minute im typing away and then the next it deletes the note. Not the whole note, But it deletes it to the same point each time... This sucks!

Me too. When i press 'done' the 3G or wi-fi starts to work then all the text I've just written disappears... How long until a fix???

I updated my 3rd generation iPod touch and iPhone 3GS last night. Everything is seems to me ok. Anyway I'm from Bangladesh. I'm happy with the iOS.

Did the 'update' last night for my 3G. Everything is now gone: contacts, email, apps, etc. the whole shabang. Thanks for making me want a droid more than ever Apple.

Upgraded my 3g and lost all my contacts last night. Upgraded my wife's 3g and it went just fine (so far). Great consistency there Apple...where's my droid?

Upgraded my iPhone 3Gs 32Gb to iOS4. Now my phone will not see any wi-fi networks. Worked fine at home and at work prior to the upgrade. I expect a few application errors with a new OS, but something as important as a problem with wi-fi should have been spotted by Apple and fixed before releasing this upgrade via the iTunes store!

1. took 3 hours to update
2.lost all email, contacts and calendar
3. connot connect to exchange server 2007 anymore due to ios4 coding glitch

phone is now completely useless.

it's my primary business phone. have to use 3 year OLD windows phone to keep in touch with Exchange 2007 as apple are incapable of keeping up with current technology. they seem to be all about pretty rather than functional. NEVER get an iPhone for business use.

Whate are you talking about? I use your setup with no problems.

32gb3gs was up and running 4.0 within half hr no problems...yet backed up and upgraded iTunes at 1pm upgraded to 4.0 @ 105pm was running by 1:40

Has anyone herd about the antena ahort problen. A friend got theirs (4g) yesterday and mine is in the mail. When you homd the phone without a case the wifi and the cell antena (which are on differend sides) the reception drops to nil. Any one hear of this.

Shame on apple for not fixing this and software before its sold.

Droid doesnt have this problem

Have been trying for three days with so many efforts the result is still zero; My iphone 3g stuck in 60% progress bar. Better stay on 3.1.3, or even better stop eating Apple, time to go to see through the window lol.

Upgraded 3G yesterday with no real problems... HOWEVER, I received my first text message after the upgrade this morning and the slide button said "slide to view" I performed the slide to view and was able to view the message WITHOUT entering my passcode. My phone was subsequently unlocked without using the passcode. I don't know about the rest of you, but that is a problem for me.

3G upgrade took about 30 min. but happened with no intervention.

Since the upgrade my 3G is basically worthless. Even iTunes is wonky. Every launched app gets about 20-30 seconds of bright white screen.

I'm eager to find out how to roll back, and barring that will go get a Droid at some place with a reasonable data network.

The upgrade went ok, but since the upgrade, a significant number of my calls go straight to voicemail, even if the phone has all the bars. Neither Apple nor ATT know how to solve this problem.

upgradation to os 4 wasnt an issue at all. Now when I add new contact it just doesnt show up in the contacts list. when i search the phone it shows up in contacts but i can edit it nor can i delete it. Also all my calendar entries dont show in the calendar but in the list view all exist. Seems i need to wail for an early update from apple on this issues.

I am seething right now! My 3G is totally messed up & even after a visit to the Genius bar today, my 'genius' confessed that his 3G has been disabled since the night before! I initially lost all my contacts, then more than 1/3 of my apps. And something really weird - in my 'password lock' app, someone else's identity, logons and passwords displayed on my screen revealing bank & credit card info! I showed it to the 'genius' and he flipped.

I have an iPhone 3GS and my upgrade went perfect. It was a text book install. BUT, I am having a problem with the Multitasking. When I double click the Home button to access the background apps, I hold my finger on the icon until the minus sign shows up but when I try to close any of the apps, the phone freezes. It seems to ba happening everytime I try this. I have to do a reset on the device. This is just as bad as Microsofts Task Manager. The same Task Manger that Steve Jobs was bad mouthing. This is extremely frustrating.

I tried two times to update my iphone 3g but the backup process hanged up at the beginning for hours. At the first time i cancelled, and at second try i left the phone connected all night. When i wake up i saw a message that says "can't complete backup, proceed wo backup" i cancelled that try too, and after i read all these here i decided to wait gor OS4.1 :))

be happy the update isnt worth it, absolutly no battery life and apps wont run longer then 5mins with out rebooting the 3g.. sucks

updated the phone with new upgrade, tried to turn the phone on and its stops on the turning on screen (the apple symbol) trying to sync the phone and now luck at all, the computer reads it, starts to sync, and then looses conection. tried different leads and different ports. same thing everytime!!!!!!!!!!

Ive started the process 3 hours ago on my ipod "3g" (technically 2g) its 8 gigs, with 7 and a half taken up. i made a perfect backup right before this that took half an hour, now its been running for almost 3 hours and its a literally ( ) this much. im seriously pissed, Apple needs to fix their crap before i get a zune.

I downloaded the upgrade & everything was going great & then when it went time for the phone to update the phone froze & iTunes stopped working & then my computer showed a blue error screen saying that i had to shut down to keep from my computer crashing. Now my iPhone 3Gs keeps coming up with this screen that says to plug it into iTunes, & when i do iTunes will not read it. I've restarted my computer & tried to restart my device but it won't work. I have a blank iPhone right now & if i tried to go to the Apple store i would have to wait in line for hours because of a malfunction with their software.

Try looking at those two knowledge base from Apple tech Support. You may have to remove the iphone driver in your device manager to force it to reinstall. Also, make sure the apple 30 pin USB connector is of good quality, and not damaged. In some cases, just getting a new cable will fix the problem.

Same here i now own a brick instead of a 3g phone.Apples attitude stinks.

Updated to 4.0 and lost all of my calendar - all of it. Fortunately, I sync through Exchange, and it's on the server and on my computer - but not on my iPhone. Very inconvenient. Probably lost 2/3 of my contacts as well. Way to go, Mac!

Absolutely ticked off!!!!! upgraded last night and after 2 hours came the pop up 'no sim card inserted' Well what do you do in this situation? no choice but to disconnect and check the Sim card right? Well I did that but still saying there is no Sim card installed. I finally reconnected the iPhone and the update started again, so peace at last and went to bed thinking all would be right by morning....WRONG!!!!!

Checked the iPhone in the morning and the update had completed, HOWEVER, it had restored itself back to factory settings and I have lost EVERYTHING.........except my itunes songs and apps (although these are also restored to factory settings and I was up to level 30 on Tapfish :(

I run a business and had every business contact in my phone in addition to every password in password wallet, so i'm P..... OFF!!!!!!!!!!!!!!!!!!!!!

I tired to upgrade today, 26th June 2010. First I did a sync, then I pressed upgrade, but the message says my "iTune" is the current version, nothing else has been upgraded. I do not know whether Apple has disabled the upgrade through iTune.

Did a normal sync with iTunes on my 16GB 3G. When I try and do the upgrade the backup stalls and after about 90mins iTunes gives me a message that the backup failed and did I want to continue losing all my data on my phone. I said no. I'll stay on OS3 for now.

All my contacts have been wiped on my 16g 3GS despite backing phone up and restoring following 4.0 software upgrade.
I double-checked that a backup had been done on my partner's identical phone before performing the software upgrade but it has done the same thing, despite being earlier told by Apple staff that if a back-up was performed then there would be no problem.
I have tried calling support staff again to no avail and am absolutely furious that this has happened again, despite assurances that it would not.
It is ridiculous that when download instructions are followed that this should happen, we deserve and explanation.

My upgrade has not gone well. All my radio applications now crash. I used the iphone to listen to international stations and now no longer. Calls drop a lot more often. Same phone, terrible reception now. Some calls go straight to voice mail for no particular reason. And now email (gmail) never loads. I am no longer able to view email on the iphone , no matter whether I am using WIFI or the ATT network.

SO it is a disaster and i do NOT recommend the upgrade. Any help will be appreciated it. thanks.

Just did the upgrade on my 3g. Lost absolutely everything I had on it. It erased my apps, pictures, all my contact info, all my emails, email information...EVERYTHING! This is an absolute disaster in my eyes. I can live without the apps as they can just be downloaded again. However, the emails and messages (that I had backed up, but apparently the upgrade deleted the backup as well) and pictures will set me back enough that I will no longer use an iphone again. I am out of town and stuck without the contacts of my business associates. Maybe I should have been more cautious, but it was a simple upgrade. This was Apples Vista!

I upgraded and wish I could go back. It upgraded fine and everthing looked great, however I now cannot access my database through filemaker. It has completely frozen and all of my clients and details are not accessible. Cannot re initialize, cannot open it, cannot work efficiently. I'm regretting updating and wish someone at Apple would fix this problem fast!

After upgrading to version 4 on my phone, it would no longer send email from Exchange server. It will receive mail, but tells me to check the server settings in the settings tab. I even deleted and then added the Exchange account with no luck. Any ideas out there? I have an EVO, and it sends mail from the Exchange account just fine, so the upgrade to 4 seems to be the problem.

I upgraded my iPhone 3GS to ios-4 just 3 days ago. Since then any body in my contacts that had more than 2 different phone numbers have had 1 number erased!! Some calendar entries have simply disappeared and the phones camera is glitching.
Man I'm not sure if I should have been one of the first!! Apple what's going on? Are the consumers now the test market??

iPhone 3G

During the update, iTunes would hang early in the process. I tried it twice before checking online if other users had similar issues. My iPhone 3G still does not have the update and nor will it. It appears that if I install the new iOS4, my phone will be permanently crippled.

It's no secret that the processor on the 3G is much slower than that of the 3GS and 4. The software environment is too complex to ever run properly on older generations.

As I have iOS3.1.1 currently installed on my phone, I hope Apple makes their iOS3.2 available again so I can bring my phone to its most current(and functionable) software state.

iOS4 totally messed up my calendar- wiped out many recent entries in iCalendar; & on its own created bizarre new ones. Wish I hadn't broken my rule of new getting rev .0 of any software.... Anyone else have a similar problem?

Upgrade took around 1 hr to complete from 3G to OS4 . pictures where originally grainy but after reboot & sync with itunes were back to normal. issue arising 3 days down line seems to be when making outgoing phone calls, connection is not made and can just hear my own voice on connection. next outgoing call would be fine. then call after that back to original issue. tried reboots but still experiencing this issue. any help welcome

WTF Apple? Are they releasing Alpha software and products? For as much as they charge for their products, they need to do proper testing on software AND hardware. My upgrade failed once and from what I've heard, I got off easy. This is COMPLETE TRASH! C'mon Jobs. get it together.

iPhone 3G

I'm just now (today) attempting to upgrade from 3.1.2 to 4.0--and now I'm wondering why the F I didn't just wait until next month when I planned to get the iP4...I started the upgrade about 1030a EST this morning and left for an appointment. It was still at the same spot when I came back so I thought maybe the Macbook going to sleep had something to do with it. I had to reboot my Mac and start again (the phone's now in restore mode w/ iTunes logo & USB). Well, the update gets to about 60% and then just hangs here. iTunes hasn't crashed--yet--but it's been about an hr since the last attempt stopped at 60%. Idk what to do now.

Actually I'd love to just go back to 3.1.2. After reading all the post-4.0 upgrade horror stories, I'm not sure I even want it anymore.

Can anyone help? How do I reinstall 3.1.2 while my phone's in recovery mode??

I knew there was new iPhone software, so opened iTunes and ran sync to be sure the fallback was good. Then I downloaded the new iPhone OS 4. Voila, everything works except there are NO CONTACTS. It allowed me to "import" the skeletal few names/numbers that were on my flip phone when I moved to the 16G 3S last June 2009. I have called support twice. No solution, but at least the second time around the tech knew where to look on the PC for a possible backup dataset. The first tech and her supervisor made it sound like the iPhone doesn't really backup the contacts; I should have known that and done it with Outlook or something else. Horsehockey!!!! When my wife's phone died it was replaced with a blank brand new one and running "sync" replaced everything flawlessly. I was told I couldn't back up and revert to the pre 4 level. There is no solution. Apple allowed me to download what they clearly knew was not robust and essentially was crap. I am very un-impressed and underwhelmed. Now I'm not even sure this won't happen again and that there isn't a flaw in my phone. I am now backing up to Windows address book, but that's not a great comfort either; it certainly doesn't heal the problem. Now a years worth of contacts, associated notes and information are gone forever. Steve Jobs, you led poorly !!!! Maybe the MMS signed off on this; it's been that level of tested assurance.

i tried to upgrade my iPhone 3G today, and i must say it was one of the most stupid things i could do!!

download went without any problems. backup, though, was taking a long time so i reset iTunes, and did my own backup. after clicking on Update again, it insisted on doing its own backup, so i just let it do that, went to lunch, and after about 30minutes later, it says it is already upgrading. after about 30mins more of that, an error message suddenly appeared on screen (forgot what it was, though), and then, nothing is happening any more. my phone is stuck on the update screen (you know, the one where a cable and the iTunes logo CD/DVD is on) and no matter how many times I do a sof or hard, reset, it still goes back to that screen.

HELP!!!! is this useless now???

for all who upgraded their iPhones to 4.0, here's a way to downgrade them...

http://lifehacker.com/5572003/how-to-downgrade-your-iphone-3g[s]-from-ios-4-to-ios-313

We have 2 iphones in the family and the first one was done without any trouble. It took over 2h to sync/backup the iphone. But the other than that no problem :)

The other one Im doing now and the backup/sync takes forever. Its been on for 23h and is only half way through................... :(

My upgrade seemed to go okay but took a while... However, following the upgrade, all my sent emails were deleted. Has anyone else experienced this following the upgrade to iOS4? Is there any way to retrieve these from old back ups?

Well my 3GS just hangs at every atempt to upgrade. My phone is a brick until Apple fixes it. I used to have a Mac and hated its little quirks. Now I am starting to hate the iPhone and its quirks too. Will they ever get the upgrade correct. I work in IT and I know an upgrade is not going to be perfect but to actually break my phone? Really?

Updated my 3G phone no problem. Maybe because I have the latest version of iTunes, and it's a Mac OS-X laptop. It did take about 1.5 hours, and it seems as though it did a backup and restore twice before it completed. But I'm not sure, because I just plugged it in and let it do its thing without worrying over it.

The only 2 unexpected results were: 1) it made me pick a new un-lock code, and 2) it made me pick a new voicemail password. I didn't recall ever having set a voicemail password, so when it asked for the old password, I just typed in some random stuff and it took it, allowing me to reset a new voicemail password.

MS Exchange integration still works fine, including calendars. No lost contacts. I have a strong suspicion that some people who have had trouble just didn't leave well enough alone during the upgrade process, and may have interrupted it after the first backup and restore.

Hopefully this will help the 3G users who have had bad luck with this upgrade.

iPhone #1 - 3G with firmware 3.1.3 = upgrade to 4.0 went flawlessly.

iPhone #2 - 3G with firmware 3.1.0 and an APN file from unlockit.co.nz installed = upgrade took much longer and when complete, the phone displayed the USB cable symbol (a.k.a. your phone is now a useless brick). I did a hard reset with no change. Did not do much troubleshooting at this point due to other obligations and after reading this thread did not have much hope. I moved my sim card from the useless brick to the working upgraded iPhone and used it for several hours today. I got back home and installed my sim back into the brick to attempt a restore and see if I could get the thing working again since all my contacts and information were on this phone. Much to my exteme surprise, the brick is magically back to normal with all my data in tact. It shows to be upgraded to 4.0 and I re-installed my APN file and all seems fine now. I used one sim card for both phones for this upgrade. I truly hope at least one of you can try this and get your phone back to operational.

My 3g is looses signal and then finds it quite often now and sometimes it cant find it and just says "searching.." I have to turn the phone off to get signal back. It really makes me angry. Is there anyone else with this problem? or does someone know how to fix it?

The simple thing is DO-NOT BUY THE I PHONE 4. i phone 3g and 3gs users have been disreguarded. now we,ve had your money we don,t care but never mind buy another phone the best way to deal with these type of industrys is to not buy there products. Hit them were it hurts.. Now if i was a conspiracy theorist i could say that apple knew the new update would cause problems for 3g and 3gs users ,but did,nt care as the new i phone 4 is all that matters now but then id be just silly to think that! .Microsoft tried the same thing with windows they release an operating system saying its the dogs bollox then a few months later release another one saying its better than the last maybe they could have added all the features in the first one ,but then thy could,nt get the same money could they?.. i suggest wait untill the price comes right down and after all the niggles have gone (but then the i phone 5 will be out).. Anyone remember when sky brought out there HD boxes? they were selling them for £250 to existing sky customers.. now there giving em away for free. DO-NOT BUY THE I PHONE 4 NOW MAKE EM WAIT MAKE EM SWEAT AND WHO KNOWS IT MIGHT COME RIGHT DOWN IN PRICE

very poor ios 4 apple should be ashamed no of my apps in iTunes so lost all payed apps sick

I'M SO MAD I COULD SPIT. Half-way through my iOS 4 update my phone locked up and went into recovery mode. I fiddled with it for 3 days, gave up and made an appt at the "Genius Bar."

They got my phone back up but everything on it was erased. I wasn't too upset because I had synced it recently and knew I could get it all back. Well NOW iTunes does not recognize my iPhone. It charges when I plug it in but my phone does not come up in iTunes.

I paid money for my apps, ringtones, music, etc and it's ALL GONE. I've lost all my phone numbers and email addresses as well.

What gives with this?!? I can't believe all the complaints I'm reading all over the net. I just want my phone back. I synced as I was supposed to but lost everything anyway.

I know there are so many posts here but if anyone has a suggestion, please get back with me. Thanks so much!!!!!!

Had trouble with the update at first, keep getting error then would have the restart upgrade. Finally got my 3G to take after 5 times. I did not loose any information from the update, but now runs very SLOW, and almost every app closes out by itself. Does anyone know if apple is working on an update for the iOS 4 or how I can restore it back to 3.1.3. PS not just my iphone but my wifes also and my daughters ipod all do the same. APPLE PLEASE FIX ASAP.

signed Unhappy iphone customer.

I don't know any other company other than Micro$oft that treat their customers like complete morons. How do these people get away with this?

My 3G is around 2 years old, it had performed like a wanna be phone but I got used to it. Only have one app on it so even though I heard about people having problems with the upgrade, I thought I would give it a try.

BIG MISTAKE!!!

after 5 HOURS of the stupid thing trying to upgrade itself, I gave up and now I am trying to go back to the old V3 s/w. My point is why this is not reported in the media so everyone can see Apple for what they are.

Mr. Jobs, I was thinking of upgrading to 4G but no way buddy. I think Android is the way to go.

Thanks for 2 years of pain!!!

I upgraded my 3GS without any issue, it took about an hour and I did not have any of the other reported issues. What I am finding though is my phone randomly freezes, I have to hold the home and power button to force the phone to shutdown. It randomly drops from my wireless network and from 3G. Applications crash a lot. I like the new OS, but the freezing is driving me nuts. Another friend did the upgrade and it took hours but no other issues. They are also having the random freezing of the phone and having to force it off to get out of the locked screen. Oh, one other thing... my space bar when typing works inconsistently.

I have a 3GS phone. Upgrade to OS4 went fine but..............

My Exchange email is now totally messed up.

1. Messages that are deleted come back. Other messages say they are unopened after I opened them.

2. Message counter shows messages that aren't there.

3. Some messages are blank and won't download.

Installes TS3398 from Apple per my Exchange server's instructions. Still having problems.

Droid is starting to look good to me.

Upgraded to 4.0 and lost most of my contacts. All my Recent calls show only numbers as their identities seem to be lost however when sending email the contact "help" list that appears with the first few letters of an email seems to still hold many of the missing contacts...???
Oh yeah, emails deleted keep showing back up. This really blows.

I've tried to do that clean (after *plenty* of attempts).

- Update to 4.01
- Restore as new
- Double hard reset

Nothing better !

I'm facing...

- Damn slow processes in basic tasks (mail, music, contacts...)
- App Crashes and even OS Crashes when using certain apps
- As it's my professional phone, I'm anxious now to open apps during the day in case of crash when someone call me !

after the upgrade to 4.0 I cannot send email via 3G [not recognising recipient and displays this message- '%@].' `i can send mail via wifi, got on to apple tried loads of thing and eventually did a full back up and restore and alas no luck.does anybody have any ideas?

Glitches with ipod and safari on iOS 4 on my 3gs. Seems slower especially maps.

After upgrade (from 3GS to 4.0.1):
1. No phone connections, no message on the phone allowed
2. No email connections
3. All application slow down, then close by themselves
4. Phone is too hot in the short time
5. In notes, text disappeared after typing
6. No multitasking (iphone froze)

is it possible to downgrade my iPhone 3G(S) from iOS 4 back to iOS 3.1.3?
I have never had such bad experience. My phone just stopped working at all.
No emails, no phone calls/messages, applications close by themselves, Calendar became empty, all my appointments have been erased.
Shame on Apple for realease without testing!

I have a 3g, which was working a treat until the 4.0 upgrade. Now I cannot sync outlook, which was one of it's selling points for me. I have tried all fixes 3 times, and have now given up.

after update of i0s4.2 on my 3g iphone i am regular faceing these problems
1.network problem.
2.battery backup is now very minimum.

how i can solve this problem kindly help me.

I was very excited and looking forward to all the features that iOS 4 update was going to bring. I successfully completed the update for my husbands phone, and mine. The next time the battery died on both phones. They completed died. I made an appointment with the Apple store, and they could not give me an answer as to why our phones would not turn back on.

atfer i had to update itunes , i plugged my 3g into the computer and of course it said there is a update for the 3g, well behold , i know have to leave my iphone 3g plugged in to use it,, shuts down within 5minutes, and when it i turn it back on i have to enter my sim code and it shows battery life is well under 20%, phone is basically useless. dont whatever u do update to 4 if ur using a 3g frist gen,,

3 failed upgrades and 2 successful restores...in the middle or restore # 3. Wish me luck!

Upgraded my iPhone 3GS 16 GB to IOS 4 and to iTunes 1o.x. All seemed to go well until I realized that all my music was missing from my phone. I did not loose my contacts and everything else appears to be ok. The backup always fails after about 10% completed. Removed and reinstalled iTunes no luck. I may have to manually save my nearly 100 contacts and restore to the factory configuration.

I updated my 3gs to the .5 software and now it wont even let me unlock my phone; it just freezes. any suggestions?

I am having similar problems the update to my Verizon iPhone 4 32GB. My phone has not actually restarted itself because of a freeze. However, my phone freezes only in the upgraded iOS software. All of my others apps (I have 65 total) work just fine. When I go into my SMS and iMessages, my camera and photos, contacts, music, etc. my phone will freeze. Once I hit the home button, it takes a moment to get there. After relaunching the app a few times, it finally lets me use it.

I love the new upgrade, I think it will be great once these bugs are fixed. But for now, it's frustrating and making me tell other users not to upgrade yet.
