I have found the perfect phone for me. The nexus one. Unfortunately I have very little knowledge on cell phones actual connectivity to they're carriers, therefor I am asking you. If I bought a nexus one, could I put a virgin mobile sim card in it and use virgin mobiles towers? The nexus one is supposed to be compatible with most American carriers so if I'm not mistaken, this would work correct? Please don't insult me if I'm wrong, I was just wondering because virgin mobile is so much cheeper and my income isn't very much. Thanks!
