I have also been watching for this functionality as well. Maybe they're holding it back until the iPhone4 adapters become available. I checked with my Dealer in the UK and the reply he got from BMW GB was that stocks were being built up, but that they then needed to be tested to make sure everything worked!! Go Figure! I would have expected testing to be done BEFORE going into production, and then batch testing to be carried out on the products. Europe was told November, then December, then end of January. Now February and still nothing.
