T-Mobile USA has taken the first commercial step in the rollout of its third-generation (3G) wireless network by launching its UMTS/HSDPA network in New York City. T-Mobile plans to continue the rollout of its 3G network across major metropolitan markets through the year.

T-Mobile’s 3G network supports voice and data services consistent with available service and handset offerings. The company today offers multiple phones that are able to operate on the UMTS network. The phones are designed to automatically connect to the best available network (3G or GSM/GPRS/EDGE) to provide the great call quality and rich communication services customers expect from T-Mobile.

Customers using a 3G-capable handset from T-Mobile will also experience faster data speeds when accessing the Web, or downloading content from the T-Mobile t-zones content portal, for example.
