It's basically the same phone as the W800 but it now features EDGE and Quadband GSM 850/900/1900/850 along with dedicated music buttons in the joystick like the W900 Walkman phone.
The phone ships with a 512MB Memory Stick and has a 2 megapixel digitam camera, 3.5mm headphone jack, Bluetooth connectivity and a 1.9-inch 176 x 220 pixel screen.
The Sony Ericsson W810i will ship before March.
