We came across this curio at Fujitsu's CES booth — the Fujitsu Toshiba IS12t is the only Windows Phone to have seen release in Japan, as far as we know, and was the first Mango phone to be released anywhere in the world. This isn't likely to ever see an international release, and there's not a whole lot to separate it from other Windows Phone devices in terms of software, but the hardware is pretty neat. The phone is fairly thin at 10.6mm, with a 3.7-inch display and waterproof body that comes in a stately black or a neon yellow or pink. There's also a 13.2 megapixel camera, which seemed to take shots of a CES booth as nicely as any other phone we've seen this week.
