iPhone OS 3.1 Beta 3 Released to Developers

Apple has seeded developers of their iPhone Developer Program with the third beta version of iPhone OS 3.1 (Build 7C116a). Apple also released a new version of the iPhone SDK 3.1, Beta 3 (Build 9M2808).

The download size is 307MB. Apple hasn't provided details about the improvements expected in the third beta version of iPhone OS 3.1.

It is expected that Apple will allow developers access to the tools they need to produce augmented
reality iPhone apps with iPhone OS 3.1.

The second beta version of iPhone OS 3.1 broke the hack which allowed users to enable tethering in the US and
other countries where the feature is not officially available.

The first beta version of iPhone OS 3.1 had revealed the following changes:

  • Non-destructive video editing means trimming a clip no longer saves
    over the original video but gives you the option to “Save as copy…”
  • Voice Control now works over Bluetooth
  • iPhone vibrates when moving icons
  • Updated AT&T profile to 4.2
  • Updated modem firmware to 5.08.01
  • Improvements to OpenGL and Quartz.
  • APIs to allow third party apps to access videos and edit them.
  • "Fraud Protection" toggle is now available in iPhone Safari settings.
  • iPhone startup and shutdown and iPhone apps launch is faster in iPhone OS 3.1.

If you are enjoying the tethering functionality using the hack then please do not update your iPhone with iPhone OS 3.1 when it is released.

The iPhone Dev team has also warned users who are interested in unlocking their iPhone 3G or iPhone 3GS
should avoid updating their iPhone with iPhone OS 3.1 (including iPhone
OS 3.1 beta) until they release tools to update firmware without
updating the baseband. They have also clarified that the warning does
not apply to first generation iPhone users as it uses BootNeuter for
the unlock, not Ultrasn0w.
