I have the Moterola Clique XT for T-Mobile and I use it on my carrier. (you can use unlocked AT&T and T-Mobile phones on it or any phone company that takes SIM cards). Well I can't get picture messaging or 3G because its an unlocked phone and their settings can't be changed to make it work on ny carrier so I wanna sell this phone and get a phone through my carrierm Thanks everyone!
