Rumours of a new BlackBerry handset that offers a slide-out QWERTY keyboard, as well as a touchscreen display, have emerged.

The Storm 3, BlackBerry 9900 or "Mr T" as the device is apparently codenamed within RIM, is described as is "a QWERTY keyboard slider the size of a Storm with a full touchscreen".

The only other info the report provides about the new phone is that the ON/OFF and SEND/CANCEL buttons will be touch-sensitive and on the screen.

The BlackBerry Storm 2 is expected to launch in both America and the UK before the end of the year, suggesting that Mr T, if all true, is more likely for 2010.
