Sony Ericsson has announced that its latest Walkman and Cyber-shot phones, the W910i and the K850i, will be available in stores from this month.

With motion-sensing capabilities, just select "Shake" control and just flick the phone to control games or skip and shuffle between music tracks. Or opt for SensMe and discover music to match your mood and tempo.

The W910i can hold around 900 of your favourite songs on the 1GB Memory Stick Micro that is provided out of the box, with room for more via the expandable memory.

The K850i Cyber-shot phone is equipped with a 5-megapixel camera with auto focus, Xenon flash and Video Light that claims to help produce true digital camera results.

Photo fix automatically improves light balance in one click and when taking a picture of a moving object, for example at a sports event, you can select BestPic and take nine pictures in one burst. Then simply choose the best and delete the rest.

The Sony Ericsson W910i Walkman phone will be available in either Hearty Red (exclusive to Orange) or Noble Black.

The K850i Cyber-shot phone has a colour choice of either Velvet Blue or Luminous Green.
