T-Mobile Galaxy S3.? Does anyone know? I am using simple mobile for tmobile right now and I want to be able to make calls there for cheap and im sure my carrier does not work there. How should I go about getting service, with whom, and where? Can I get set up and ready here in NY or should I wait till im in DR? Also how much $ am I looking at? Im all unlocked and ready to pop in a different SIM. Thanks.
