This is the card that a lot of the later Sony Ericson phones use for there memory.
They were previously £17.99, but have now reduced in price to a ridicuously low £15.49
This M2 card comes with a Pro Duo adaptor which allows you to use it in other devices, most notably the Sony PSP.
These are magic gate supported, and I personally have 2 of these that I use in my PSP's that have custom firmware on.
