Yesterday Apple seeded a beta of iPhone 3.1 to developers to test with their applications. Although not listed with release notes, iPhone 3.1 comes with quite a few noticeable improvements as well as bug fixes. Forum member 370GT pointed out that 3.1 now comes with the option to save edited video as a copy instead of overwriting the original. He also pointed out that the phone vibrates when you start moving icons, and Voice Control now works through bluetooth headsets. We've also noticed that boot time has been greatly improved. Also noted yesterday, MMS is enabled by default in 3.1, although the required service option hasn't been enabled by AT&T.
The Dev Team posted a warning on their blog reminding users that if you want to maintain the ability to use the Ultrasnow unlock for the 3.x firmware, don't upgrade to anything past 3.0, including the recently seeded developer copy of the OS 3.1 beta. 3.1 updates the baseband, breaking the ability to be unlocked by the Dev Team's exploit. The warning applies only to 3G and 3GS devices.
BrightKite announced on their blog yesterday that the native version of the popular social network has entered private beta testing. The posting didn't offer many clues as to what features would be included in the finished version, although it did note that the app is not yet feature complete. The beta program quickly closed as Apple only allows each developer 100 ad hoc authorizations. Those who made it into the program are required to send information on bugs and possible ways in which to improve the app before its submission to the App Store.
