as far as i know, bluetooth on the iphone is very limited. i am only aware of it working with a head set or some other accessory such as that. i didnt even know that it was possible that you could sync it with itunes
Its not possible. And for good reason, a song sync could take ten minutes each. Even just the contacts and other data would take bit, although not too bad. I wish there was a Bluetooth sync option that automatically ignored music, photos and vids.
