T-Mobile officially announced their G1 smartphone this morning, the first handset to use Google’s Android platform. The G1 is a dualband UMTS, quadband GSM slider with a full QWERTY keyboard, trackball and 3.2-inch 320 x 480 HVGA capacitive touchscreen for navigation; it also has GPS, WiFi, Bluetooth and a 3.2-megapixel fixed-focus camera. Our sibling site Android Community were on hand to get some hands-on pictures and video.

G1 talktime is estimated at up to 350 minutes WCDMA or 406 minutes GSM; standby at 402hrs or 319hrs for WCDMA or GSM respectively. The battery, unlike that of the iPhone, is removable. However HTC have used their own mini-USB connection rather than giving a normal 3.5mm headphone socket, so you’ll need an adapter (apparently not supplied in the box as standard) if you want to use your own cans. Internal memory is a mere 256MB ROM and 192MB RAM: all storage is via microSD, with a 1GB card included and up to 8GB supported.
