you can get an adapter like the scosche passport to convert the pins to charge the iphone. i'm not sure if it will work with the BMW interface but it did work in my girl's benz.
To add a confusing data point, the recently dealer installed MOST IPOD interface on my '07 335 DOES IN FACT
charge the iPhone 3G.
It also plays music and sends/receives calls while hooked up. It did give the "device not designed, blah blah, do you want to put it in airplane mode?" I answered No.
