Sony Ericsson has just released their much anticipated xperia pureness mobile, with its unique see-through
screen. The pureness features an opaque black keypad and a contrasting 1.8” display, which is almost
completely transparent thanks to its glass blacking.

The phone will be released in limited markets being sold at fashion retailers such as Sak’s and Collette.
