Native iOS 5.0.1 Jailbreak Released

iPhone Dev crew member Musclenerd is proud to announce availability of Redsn0w 0.9.9b9, an updated version of their notoriously simple jailbreak that adds native support for iOS 5.0.1. The hack is tethered for now.

According to the hacker, this version of Redsn0w “will let you do that 5.x replay attack”. It supports pretty much all iDevices that have an A4 processor or lower (iPhone 4S and iPad 2 not supported).

Musclenerd directs Twitter followers to an update on their blog, where the Team notes that, “even though we always recommend that jailbreakers stay where they are until a new untethered JB comes out, that’s not always possible.”

“So we’ve updated redsn0w for those who may have found themselves at iOS 5.0.1, and added some other useful features too.”

According to the hacker, this Redsn0w offers native support for iOS 5.0.1, which means all of the functions provided by the hack tool are a go. Those include: “Jailbreak”, “Just boot”, “Fetch blobs”, “Stitch blobs”, “Recovery Fix”.

Another notable addition is the ability for 3GS owners to create custom IPSWs without blobs. This works only with old-bootrom devices.

It brings ultrasn0w compatibility for 5.0.1. This is said to become available on Cydia Monday (today).

The new 8GB iPhone 4 is supported as well. Owners of this device had problems with “fetch blobs” up until now, according to Musclenerd.

An upcoming update to this version of Redsn0w will allow Windows users to use the “Custom” button to create IPSWs without baseband updates.

iPhone 3GS owners have an important aspect to note, in that they must not flash the iPad baseband. Musclenerd explains: “The iPad baseband will not work on 3GS iPhones built later than 2011 week 35. You have a week 35 or later device if your serial # starts with xx135.”

Other notable additions (as posted on the team's blog) include:

· accommodates APTickets in 5.x (until next Apple countermove). APTickets are crypto-verified before submitting to Cydia, just like the main blobs. Cydia server support for sending back the APTickets is upcoming. For now, use stitched IPSWs for 5.x. Due to APTickets, stitched 5.x IPSWs now require user to start in “Pwned DFU” mode
· support added for stitching 4.x blobs to iPad2-GSM IPSWs. Similar to @notcom’s TinyCFW but doesn’t require lots of RAM or a TSS-assisted restore. Won’t work for iPad2 5.x blobs (or iPhone4S at all) until a bootrom-level exploit is out
· top line now shows whether (and where) a redsn0w update is available, or if the version being run is the latest. Uses DNS TXT record to alleviate any concerns about snooping
no 5.1 beta support at this time (major apps like Cydia are not yet compatible)
@pod2g has been doing a great job porting his 5.x untether…check his blog for updates!
