Not sure of who's providing the service? I'm in Canada and luckily through a couple contacts i've played with the phone and it was quite impressive in the Silver. Same performance as the GD55 but with a little longer talk and standby. Other than that the only glitch I find is that the keys are like slivers. Same little tick that got me away from buying the G50. As for providers, probably one in Asia. AT&T won't carry and neither will the other providers.
