Good news for iPhone users. iOS6 is finally supporting iDrive Office integration via Bluetooth MAP(Message Access Profile). Bluetooth MAP is the protocol used to retrieve email messages through iDrive, which currently only works with Blackberry and a few other devices.
Couple shots of my wireless non USB connection using my iPhone 4S with iOS6 Beta 1. iOS6 Beta 1 is still a little buggy but this is a great start. I suspect the (Sender Unknown) header will be fixed with the next beta release.
I am also running the latest Connected Drive Bluetooth and USB update from BMW.

Update 06/25/2012: iOS6 Beta 2 released today. The senders name now displays in the message header. SMS Messages are still flagged as Email and not text messages but are still readable and functional.
