If you head on over to the iPhone Dev Center right now, you'll see that SDK 3.1 beta 2 is now up and available. Included in the changelog are a few APIs for customizing video/picture control looks.
It's also reported that the baseband has also been updated in this release to 05.10.01. An urgent reminder for those with unlocked phones, or those who would want to unlock in the future: do not upgrade yet if you hold your unlock prospects dear.
- New updates for Ultrasn0w and reds0w now available
- iPhone Dev Team: stay away from any updates to 3.1
