A handheld wireless communication device includes a device body having a display screen. The display screen is located above a four-wheeled user input device located on a front face of the body. The four-wheeled user input device includes a set of four rotatable wheels, each mounted on an axle having a longitudinal axis oriented substantially perpendicular relative the front face of the body. At least one sensor is operatively associated with the set of four wheels and is configured to sense motion induced in any of the four wheels. Additionally the at least one sensor is further configured to output electronic data representative of sensed wheel motion. The device further includes a microprocessor that is programmed to process input data into cursor guidance instructions that are outputted to the display screen and which affect x-direction and y-direction cursor movement on the display screen in correspondence with the sensed wheel motion.
