Has anyone got a wrist-mounted, sliding, Spider-Man-style mobile phone yet?

Only the patent for one was registered back in 2004, so they really ought to be on the shelves of Carphone Warehouse by now.

The invention is officially known as a “Device for the Quick and Easy Use of a Small Size Cellular Telephone,” and involves hiding a phone up your sleeve, with a little extendable sliding tray flipping it out into your hand. This would save valuable seconds in answering those weird wrong numbers.
