iOS 5.0.1 released to address battery drain issues – Jailbreakers SHOULD NOT update

Apple has just iOS to the public, bringing fixes for battery life issues introduced with iOS 5. The release also brings several other enhancements including multitasking gestures for the original iPad. Both @MuscleNerd and @pod2g warn to stay away from this update if you are planning on using the future untethered . Besides fixing the battery issues, iOS 5.0.1 also patches the signing that Charlie Miller revealed last week which is the method pod2g plans to use on his untethered jailbreak. It's very important to remember that Apple has changed the way the firmware is verified in iOS5 so there is absolutely NO WAY to downgrade back to iOS 5.0 once Apple has stopped signing it.

For those who don't care about an untethered jailbreak, you should be able to update over the air, although some users have been reporting that the update is not yet available over the air. For those who it isn't available for now, it should be soon, otherwise you can always use iTunes to update.

Changes:

  • Fixes bugs affecting battery life
  • Adds Multitasking Gestures for original iPad
  • Resolves bugs with Documents in the Cloud
  • Improves voice recognition for Australian users using dictation

The build number on the public release is 9A405, an increment of one build over the beta 2 build seeded to developers last Friday.

iOS 5.0.1 is available for iPhone (4S, 4, and 3GS), iPod touch (third- and fourth-generation), and all iPad models. The update is available for download via iTunes or OTA.
