The invasion of Linux-based cellphones has begun, beginning with the Grundig U900. This Chocolate-lookalike clamshell features a couple of cameras – one in front to take advantage of the UMTS 3G connection, while the 2 megapixel with flash camera behind is used to capture candid moments. Additional features include a built-in FM radio, Bluetooth and USB connectivity, video and audio playback, and 100MB of internal memory. In case that is not enough, you can always bump it up with a microSD memory card. The 2″ QVGA 262k color display that comes with the U900 is pretty standard these days though, so nothing special there. Pricing and availability details are still unknown.
