A mobile telephone includes a body, a display, and a keypad. The keypad has a plurality of individual numeral keys assigned to individual numerals and may be rotated with respect to the body. In this way it is possible for the presentation of information on the display to remain in a fixed orientation with respect to a user while the body is rotated about the display so that the mobile telephone can be converted from right-handed to left-handed use or the display can be moved from a first orientation to a second orientation.
