T-Mobile unveiled its G2 Google smartphone with 4G. The phone is the first designed for T-Mobile's HSPA+ network, which the company says covers 100 million Americans in more than 55 major metropolitan areas across the country. The G2 is of course the successor to the G1, which was the first Android-powered phone. It is designed by HTC. It has a 3.7-inch screen and opens to a QWERTY keyboard, and comes with Android 2.2 and a snapdragon MSM7230 mobile processor.
