Several sources are confirming today that T-Mobile is preparing to deploy 21Mbps HSPA+  service to at least four markets on March 14.

According to a report from the Android site AndroidandMe, markets for T-Mobile’s faster 3G service include Dallas,  Miami,  Los Angeles and Chicago. The site also suggests that Philadelphia may be a market, as the company is currently testing its HSPA+ technology in that region.

The first device slated to be compatible with T-Mobile’s faster network is the webConnect Rocket, an HSPA+ USB adapter for laptops. Early speed tests on the WWAN adapter show speeds of approximately 10/3Mbit up/down, and a latency of just 72ms.

With respect to compatible handsets, however, it is not clear when T-Mobile will offer phones that feature the necessary HSPA+ radio; speculation suggests that such phones could appear by the fall of 2010.

Pricing for the new service is not yet available.
