As well as the TG02, Toshiba's brought the K01 slider phone all the way from its Japanese R&D department to Mobile World Congress, showing off a very nice sounding 4.1-inch OLED screen.

It's a bit thicker than the TG02 at 12.9mm deep, mostly due to the addition of a QWERTY keyboard. A 1Ghz Snapdragon processor, and microSD card slot are all that's known about the K01, until we grab some more information (and pics) from Toshiba.
