In this Oct. 5, 2010 photo, an HTC G2 phone from T-Mobile in San Francisco, is displayed. Two years ago, the Android invasion began when T-Mobile released the first smart phone running Google's Android operating system, HTC's G1. Since then, a parade of increasingly capable Android phones have hit the market, making the G1's then-cool touch screen and side-sliding QWERTY keyboard look quaint. The latest is the G1's successor, the G2. The basic design is similar, but the phone has gotten a major overhaul in terms of style, speed and functions. (AP Photo/Eric Risberg)
