I'm sure UCrew can elaborate more on this, but Verizon made Motorola disable a lot of features that were designed as part of the phone, most notably is the bluetooth functionality. Verizon wants to make sure you buy your ringers and such from them, not just copy them yourself. There are hacks for the 710 and even more for the 815 to get around this. http://www.howardforums.com/forumdisplay.php?f=294

Hope this helps.
