Bluetooth and un-supported phone, idrive screen flicker

[s54mseries]

Just took delivery of a 2008 3.0si three weeks ago. Upon delivery and the training deal the serivce guy linked my att motorola razr v3 (blue one) and everything seemed to work regarding the address book sync, making calls, getting calls, etc. After three days of the car in our possession the idrive screen upon startup would just flicker with a white bar in the middle.

Took the car in for service on a friday night just as they were closing. Luckily got a loaner x5. Got a call that following tuesday that the car was ready and just needed to be reset whatever. They couldn't find any faults in the electronics and being that the car only had around 350 miles on it. They could only deduce that it 'MAY' have been caused by my cell phone. The motorola that i use is not on the bluetooth approved tested list. There is no guarantee that any bluetooth phone would work. Only the iphone 3g, blackjack something and two others are listed on bmwusa.com.

Anyone have a similar problem with the idrive, bluetooth, and un-supported phones?
