T-Mobile USA, the nation’s fourth largest carrier, will be upgrading its 3G network to 7.2 Mbps HSPA by the end of 2009 with an HSPA+ to faster 21 Mbps data speeds in 2010. Current devices, including the MyTouch 3G, the T-Mobile G1, and the Motorola CLIQ will be able to take advantage of the 7.2 Mbps HSPA speeds. News of the fast network upgrades should be welcomed for customers of the carrier; T-Mobile was the last of the big four to implement 3G.

The carrier has already begun deploying its 21 Mbps second. Philadelphia is the current testbed for the fast data transfer speeds.
