I have a VZW 8330 (Curve) and don't want to use VZNavigator (it stinks). I am looking to purchase a dedicated GPS unit that I can also use with my phone (I have an unlimited data plan) to get traffic updates, etc. I bought the TomTom Go 720, but of course VZW won't allow data access with it because there's no OBEX transfer allowed on the bluetooth. Anyone know of a unit I can use or a way to get OBEX to work on the phone?
