im assuming your in las vegas because their one of the few places that have triband. metropcs is also triband in las vegas. from how i understand it, triband is like gsm or cdma your phone either made that way or its not. example is you cant take a att phone over to sprint and expect them to activate it its a totally different way it picks up signal and transmits to the towers. i could be misunderstanding it, but i doubt it.
