Dubious "spy" pictures have been doing the rounds for a little while, but today Sony Ericsson officially launched the W52S in Japan.

A colourful slider, this new addition to the WALKMAN music phones family looks likely to only be available in the Far East from June.

You could say that everything about this phone is on the large side.

It's packing a huyuge 2GB memory, a 2.7-inch screen and battery capable of over 100 hours of music playback.
