OS 3.1βリリース

iPhone OS 3.1B がデベロッパー向けにリリースされたみたいですね。
ベースバンドのバージョンが変わることから、JailBreakとアンロックする人は、Devcheamからの正式アナウンスがあるまで、バージョンupしないほうが良さそうですね(⌒-⌒; )

以下、iPhone Hacks より記事抜粋。

•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.
•There are also reports that MMS feature is enabled for AT&T users but it does not work as for some reason it hangs and fails before MMS goes out.

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.
