iOS 5.1 beta 2 hits dev center
Apple on Mondahy posted iOS 5.1 beta 2 to the Developer Center. Along with cleaning up the release, 5.1 now gives an option of deleting photos from the Photo Stream and seeing those changes propagate elsewhere. Photos have to have been taken with an iOS 5.1 device, however, and they will only automatically vanish on other iOS 5.1 hardware.
Also arriving are a matching Apple TV beta and a beta of Xcode 4.3. The new developer kit is arriving as a lone app bundle that lets Xcode install directly from the Mac App Store for the eventual public release rather than having to unpack an installer. Developers during the test phase will still have to open a disk image, but they can just drag the one icon to the Applications folder on the Mac.
Most of the earlier teething issues from beta 1 appear to have been fixed and hint at Apple getting closer to launch. It's not known if beta 2 has any improvements for lingering battery life issues.
The release follows Apple's habitual two-week beta cycle. Apple might skip any betas two weeks from now, however, as many are likely to be out for Christmas holidays.
