I have the non-idrive base radio.
My iphone 4 wont play music through the USB, but the battery will charge with a regular apple usb cable, gives a 'not compatible cable' message when plugged in. Works OK with the supplied BMW USB/3.5mm Y cable for playing music.
Memory stick works fine.
Bluetooth works fine with the iphone 4 except it wont voice dial from the address book in the phone, have to manually store names/numbers in the car or search numbers manually with the radio/steering wheel buttons.
High tech it isnt
