The device does appear to be quite similar to Nokia’s N900 with the exception of the slide down QWERTY keypad. It comes equipped with a 4.3 inch resistive touchscreen and a 3.2 megapixel camera on board. It’s a 3G enabled device that uses an 806 MHz Marvell ARM processor its functions together with 128 MB of RAM.
