Does it reconnect if you don't use the cradle? Do you mean connected for Bluetooth calls only or connected for BT audio and BT calls?
I lose BT audio if I connect the USB to my iPhone 4 but iDrive warns me if this will happen. Other than that no connection problems at all with two paired iPhone 4s, both on latest version (4.3.3). Previous iPhone 3Gs had no problems too
