Sony has announced the launch of its Memory Stick Micro (M2) card "value-added" line-up offering more storage capacity for mobile phones.

The line-up contains a handy M2 USB adaptor - making it even easier to transfer files between the Memory Stick Micro card and a PC.

Described as ideal for anyone who doesn't have a computer with a built-in or Memory Stick card reader. The new range is available from 512MB up to the new 4GB capacity.

The new line-up, including the M2 USB adaptor as well as the 4GB capacity version of M2 card will be available from November 2007.
