An auction site is putting an unknown Sony Ericsson 123 prototype under the hammer. Apparently this one is supposed to be the successor of W880. The phone on auction is a slim walkman phone with a probable model name W890. Purely based on the speculations, the W890 is supposed to have a 3.2-megapixel autofocus camera, Bluetooth, 2-inch QVGA display screen and a metallic body.

The Walkman W890 phone supports UTMS connection, plus a secondary camera is also on the front for video calls. Like the W880, the W890 has a 12mm slim body with a usual Walkman control keypad
