T-Mobile USA has confirmed HTC as the manufacturer of its forthcoming HSPA+ smartphone, the G2. The Android device will be the world’s first HSPA+ smartphone and boasts a 3.7-inch touchscreen as well as a full Qwerty keyboard. It runs Android 2.2 and a Qualcomm 800 MHz Snapdragon processor, and has a 5 MP camera and an HD video camera. T-Mobile USA has not yet revealed pricing or availability details, but said its existing customers will be able to preorder the device later this month.

The G2 will follow in the footsteps of HTC’s G1, launched by T-Mobile in 2008 as the world’s first Android smartphone. T-Mobile USA is heaviliy marketing the G2’s HSPA+ capabilities, as the operator claims that 100 million Americans in more than 55 major metropolitan areas are now covered by the technology. It aims to reach more than 200 million people by this year. T-Mobile USA’s HSPA+ network currently offers theoretical peak download speeds of 21 Mb/s, and the operator plans to increase this to 42 Mb/s peak speeds in 2011. However, the G2 device has a theoretical peak capability of 14.4 Mb/s.
