Looks like T-Mobile may have some substantial plans to put high-speed 3G cellphone services into play here in the US. According to senior vice president of Engineering Operations, Neville Ray:
The company is currently undertaking 3G testing in some markets, though he would not reveal specific locations.
Ray also said that he hopes to see the service in use by the end of next year, and most definitely by 2007. Of course, don't hold your breath for full 3G services, as "some" seems to be a big word here. And it also has to do with a cellular spectrum auction that should be held by the government next summer.
