T-Mobile formally announced the rollout of its 3G wireless network. The new UMTS/HSDPA network launched in New York city and other cities will follow through the rest of the year. By the end of the year, T-Mobile should be offering 3G service in those cities where, according to its press release, a majority of its subscribers currently use data services.
As reported earlier, the network will support voice and data services. T-Mobile is so far offering four UMTS devices (the Nokia 6263, Nokia 3555, Samsung T639, and Samsung T819) but plans to unveil its first HSDPA device within the next few months. It also promises other data-centric, all-in-one devices.
One caveat: Because T-Mobile uses a different frequency from other 3G carriers in the U.S., you will need to check that any unlocked device you purchase supports the 1,700MHz band.
