New Bluetooth Features
Bluetooth on the iPhone hasn't quite caught up to the rest of the world yet, but iPhone Software Update 3.0 does fix a lot of the problems. We'll continue pining for Bluetooth file transfers, but in the meantime Apple has added Internet tethering and A2DP stereo audio streaming to the list of tricks; both are nice additions for those on the move. Apple has also added peer-to-peer connections via Bluetooth. In the future this will enable you to play multiplayer games between iPhones without unwieldy Bluetooth connection procedures.
