For the Verizon peeps lurking around, there appears to be an update out for the V710 called the Motorola e815. According to initial reports, this phone pairs with the BMW BT ULF and also uploads the address book to the BT ULF module. Dimensions of the phone are the same as the V710, so the cradle may also be the same. See
