Apache server logs have revealed that requests from phones running two distinct iPhone Software 2.0.1 builds are coming from the San Francisco Bay Area (near Apple's Cupertino HQ) and Atlanta (where AT&T is at). It is believed that OS 2.0.1 will resolve the issues emerged with some iPhones after the 2.0 update last Friday.

AppleInsider could confirm that build 5B101 is aimed at first-generation iPhones, while build 5B103 is targeting the new 3G device. "Although Apple began testing the updates prior to the official release of iPhone Software v2.0 on Friday, neither have made their way into the hands of iPhone developers," the site notes.

This week, Apple Discussions has revealed that dozens of iPhone users are experiencing crippled camera applications, and some issues with the accelerometer on the new iPhone 3G, after upgrading the phone's software. Some users claimed that, after updating, it took a full six seconds for the camera application to launch and the digital shutter to open to be able to take a photo.

"I have an original iPhone and after updating to iPhone update 2.0, my camera got noticeably slower," a user wrote. "I would say unacceptably slower. It takes around 6 seconds to launch, 3 seconds to return to camera after viewing recent photos, and six second to take a photo after the last photo is taken!" Because of this, some users are quite disappointed by not being able to take spontaneous photos.

As for the second issue encountered after the 2.0 update, others complained of bad responsiveness on behalf of the iPhone 3G's accelerometer: jerky responses, unintentional landscape shifts, or no response at all after the handset sleeps, are just some of the issues pointed out by AppleInsider.

"My accelerometer is also having problems," a disappointed 3G owner wrote on Apple Discussions. "It works perfectly until the iPhone sleeps for 30 seconds or more - when it wakes the screen no longer rotates (in photos, safari, calculator, etc)." He added that "accelerometer based games behave as if the top of the phone is pointing down to the ground," while other motions still have an effect in the same application. "...it seems to be just one of the 3 accelerometer axes that is reporting the wrong value," the user concluded.

Apple hasn't said a word about whether software update 2.0.1 for iPhone and iPhone 3G is even being tested, let alone mention the issues it is aimed at. Nevertheless, nasty bugs such as the ones mentioned above simply can't be ignored, so it is safe to assume that iPhone software 2.0.1 is coming to the rescue.
