Does anyone know what the iPhone bluetooth version is? As far as I can tell, it's using a bluetooth version that does not support text-messaging/file transfer. I could be wrong. This is kind of sucks, since alot of vehicles are now coming with hand-free calling/text messaging - like Fords. I have Ford's Microsoft Sync in my car, it works like a dream with my Sony Ericsson. It reads my text messages to me, and I can even reply. But, Ford Sync only works for voice with my iPhone, and no music streaming! Most enthusiasts are stating it's due to the bluetooth version of the iPhone. Has anyone heard anything on this issue? And if Apple will be updating the bluetooth version to support more than just voice?
