iPhone kinda supports playing any audio through a bluetooth headset

As I understand it, there are a lot of new DAPs and music-enabled mobile phones that support A2DP - a technology that allows devices to transmit stereo audio to Bluetooth headphones. It's all the rage with the kids these days, and many fans of cutting cables wherever possible were a bit disappointed when the A2DP acronym didn't make the iPhone's feature list.
