T-Mobile is proud to announce that they have sold more than a million of their Android-powered G1 smartphones in about 6 months. Launched in October, the G1 slider with QWERTY keyboard and Google services obviously is worth the bucks that they spent on the ad campaign. Although the Storm only took half that time to reach a million and the iPhone merely a weekend, we expect that the good news will spur on Samsung, Sony Ericcson and Motorola to hop on the Android bandwagon.
