The UMTS-enabled W850i arrives with TrackID, powered by Gracenote Mobile’s MusicID application, which allows users to record a few seconds of a song and send it with one click to the Gracenote database for identification. Recording can be done via the microphone or directly from the built-in FM radio.

The phone is loaded with Walkman 2.0 software for music playback and management and comes with a 1GB memory stick expandable to 4GB. It’s also configured to work with operator over the air music download services.

The second new device is the W710 Walkman. This one’s aimed at the gym crowd, with a built-in motion sensor that measures running speed, distance, time or steps; it’s the first pedometer phone. The W710 comes supplied with a 512MB Memory Stick.

These announcements perpetuate an extraordinarily busy year for Sony Ericsson. The manufacturer has just revealed the Z710 and Z550 clamshell phones, which brings the total announced in Europe this year to 17.
