Sony Ericsson has announced a raft of new phones, including two Walkman and two Cyber-shot models, today in London.

Rumours of the hotly-anticipated W880/W888 were circulating online last week, and now we finally have confirmation of the specs.

It does indeed measure just 9.4mm thin, comes with a 1GB Memory Stick Micro, and features a 2MP camera.

The Walkman phone, which comes in either Silver or Black, is bundled with Disc2Phone music management software, and features Bluetooth Audio Streaming, 18 hours of music listening time, and Flight mode.

The W880 is a 3G phones, while the W888 has been designed especially for China where 3G services aren't established yet.

The W610 looks more like other Walkman models, and can store up to 470 full-length music tracks on the bundled 512MB Memory Stick Micro. It also features a 2Mp camera, horizontal camera menu, Picture blogging, and FM Radio; colour choices include Plush Orange and Satin Black.

Look out for the W880 in the first quarter, and the W610 in the second.
