Portable communication devices integrate functions such as radiotelephone capabilities with messaging or personal digital assistant (PDA) functions. A foldable portable communication device (100) to accommodate the space limitations while providing the necessary tool to operate the provided functions comprises of a first housing portion (102) and a second housing portion (104) each having a user input, such as a QWERTY keyboard (118, 130). When the device is open, the portable communication device operates in one mode, such as messaging mode and utilizes both user input devices on each housing. A display (132) for displaying text is located between the first housing portion and the second housing portion. In the closed position, the first housing and second housing are coupled together and user inputs are used for a separate mode in the closed position, such as radiotelephone mode.
