HTC Desire Z (Unlocked Quadband) GSM Cell Phone The HTC G2 is the successor to 2008's much ballyhooed HTC G1 (aka the "Google Phone"), the very first Android smartphone released in the United States. It's also the first T-Mobile phone built to take advantage of the carrier's new, faster HSPA+ 3.5G network; it can handle theoretical throughput speeds of up to 14.4 megabits per second. The G2 runs a newer version of Android (2.2, or Froyo), features a smart design with a pop-out physical QWERTY keyboard, has an 800MHz Snapdragon processor, and sports a larger and better-looking touchscreen.
