T-Mobile USA has just announced the expansion of its 4G mobile broadband network to 10 additional local markets.

After this new move, the carrier is offering 4G services to 167 markets and more than 200 million people nationwide.

The carrier is currently expanding to Ames, Iowa; Anderson, Indiana; Battle Creek, Benton Harbor and Jackson, Michigan; Fort Collins-Loveland, Colorado; Lawrence and Manhattan, Kansas; Springfield, Illinois and Wichita Falls, Texas.

Furthermore, T-Mobile USA also revealed that was doubling the speed of its HSPA + network to achieve a theoretical download speed of 42 Mbps.

According to the carrier, the first customers to take advantage of the new speeds will be those living in Las Vegas, New York and Orlando, Fla., followed closely by Chicago and further expansion of the New York network into Long Island, N.Y., and Northern New Jersey.

More than 140 million US customers in over 25 markets are expected to have access to these increased 4G speeds, by mid-year.

- 4G Smartphones: the Galaxy S 4G, the T-Mobile myTouch 4G, the T-Mobile G2 with Google, the upcoming T-Mobile Sidekick 4G by Samsung and the upcoming T-Mobile G2x with Google.
