Promising a standby time of a month the new keyboard will emulate the BlackBerry Pearl and feature two keys per key on its 20-key keypad.

As well as E55's "compact" QWERTY keyboard there's one click access to the most commonly used programs.

The E55 also offers full Nokia Maps, assisted GPS and comes with N-Gage on board. It will also feature a 3.2-megapixel camera.
