Fujitsu has launched what looks to be the world's first waterproof mobile phone, but the company is only claiming that it's the thinnest waterproof mobile phone.

The F703i, which probably won't be making its way across the world from Japan to other markets, measures just 17.9mm thick and can apparently be submerged for half an hour.

It can only go down to a depth of 1 metre, but who's really going to go swimming with their mobile anyway?

Features of the shiny-looking device include a 2.2-inch screen, a 1.3MP camera, and a webcam for video chatting.

It also has a MicroSD slot for extra memory, although we can find nothing about a music player.
