The HTC EVO 4G draw some attention to Sprint's WiMAX network, but T-Mobile has also been hard at work at expanding its HSPA+ footprint. In case you forgot, T-Mobile HSPA+ is a high-speed wireless network that is able to theoretically pump out speeds of up to 21 mbps.

There is a real WiMAX 4G vs HSPA+ competition going on. And T-Mobile's network is actually holding its own as Sprint's WiMAX 4G network is still immature.

Here are the latest markets in this major T-Mobile HSPA+ footprint expansion:

• Los Angeles
• Dallas
• Atlanta
• Houston
• Seattle
• Tampa and Orlando, Fla.
• Pittsburgh, Charlotte, Greensboro, and Winston-Salem, N.C.
• Oklahoma City and Tulsa, Okla.
• New Orleans
• Charleston, S.C.
• Bentonville, Ark.
• Anderson, S.C.
• Fayetteville, N.C.

These new markets are expected to be live with HSPA+ by the end of the month, creating a footprint that covers 75 million POPs across the U.S.

This latest round of expansion places T-Mobile on track to have 100 major markets and 185 million people covered by HSPA+ by the end of 2010.

Tune in for more news and updates on T-Mobile's HSPA+ wireless network.
