Disclosed is a mobile communication device for searching data based on a rotation angle. The mobile communication device includes a body; a geomagnetic sensor for detecting a rotation angle of the body based on an axis perpendicular to the earth surface; a main memory for storing an image corresponding to the rotation angle; a display unit for displaying the image on a screen; and a control unit for, if the rotation angle detected in the geomagnetic sensor is changed, extracting an image corresponding to the changed rotation angle from the main memory and controlling the display unit to display the image. With this technology, data can be searched conveniently without manipulating keys many times.
