More features are being discovered in the first iOS 4.1 beta, which was released to developers on Wednesday. In the long term the most important is proper AVRCP support for Bluetooth devices. Until now, headsets, car dashboard systems and other peripherals have been unable to control more than volume for Apple handhelds. Actually controlling playback has required using the iPod app, a potentially serious distraction; with AVRCP however, it should also be possible to skip forward and back through tracks using buttons.
