I have a question which maybe only Hugo can answer: How come the iPhone does not have A2DP support?

Its supposed to be "The best iPod" right, and it has Bluetooth already... I really don't understand why this feature was left out. There are quite a few Sony Ericsson phones out there with A2DP allowing wireless streaming to Bluetooth headphones, Bluetooth Stereos (Sony make a few) and a few car headunits and new Bluetooth car kits as well. It would be nice to play music from the iPod and take calls all in the car without any cables. All the hardware is there already anyway, right?
