If you just unpacked your iPhone and you've got yourself a BMW 3 and 5 Series with 03/07 production, the X5 with 04/07 production and the 6 Series with 09/07 production dates equipped with an iPod/USB interface — guess what? You'll be able to drop the iPhone into your ride and faster than you can say "Boom!" in your best German accent — you'll be good to go. Or at least that's what we've learned from the following site that's just been pointed out to us below. What level of integration that means, we've no idea — but since BMW was the first to provide iPod support, one should expect they'd be first out the gate with iPhone support. – Ray Wert
