I have the v710 and Verizon in the cincinnati area. I can tell you that it does not sync with iSync via BlueTooth, but does with the USB cable from Motorola. It does not transfer files via BlueTooth nor the USB cable. I don't even know how you would do it via USB either. BlueTooth File Exchange clearly does not work. As someone stated earlier, it can communicate with your Mac, but only to dial (gee, whoopie). I'm not sure who is to blame (Apple or Verizon), but I highly suspect it is Verizon as they are your typical nasty large corporation very comparible to Microsoft in my opinion. For example, they don't want you to exchange games and ringtones I buy with my wife's phone when they can make her buy them too. I can see no reason why Apple would cripple BT syncing with iSync. I have never tried the "fix" mentioned in this thread, but I just might. Thanks to all who have contributed to the thread!
