Unfortunately for U.S. buyers the phone will only be arriving in the UK at that time, pretty much in line with Microsoft talks back in August.
It's also being reported that all five of the UK's major phone operators will carry Windows Phone 7 devices.
The screenshot above is the HTC Mozart which offers a 3.7-inch 800 x 480 pixel TFT LCD, 1GHz CPU processor and 8MP camera (Xenon Flash, 720p video recording). The Mozart also offers a decent 1300mAh battery and comes with 8GB memory.
Throw in Bluetooth 2.1, A-GPS, and 802.11n WiFi and you have a good deal of connectivity for one of the first Windows Phone 7 devices you'll see.
