I've got a RAZR V3m phone, and the instructions offer very little in the way of telling you how to transfer files from the computer to the phone. (probably because they want you to pay for their download service) A weird little usb cable came with it, but the end of it is NOT compatible to a standard USB cable, so I'm stuck. Where can I get a compatible USB adapter without paying for the overpriced "music essentials" kit from verizon??
