The present invention is a portable communication device with an interchangeable user input module including two input devices, each disposed on one side of the module, opposite each other, to accommodate multiple functions, space limitations, and size reduction. Two or more features are often combined into one portable communication device to increase functionality. Input devices need to be interchangeable in order to facilitate the multiple features, for example, phone, messaging, personal data assistant, and gaming capabilities, of a portable communication device. The reduction in size of portable communication devices leads to space limitations for input devices. Each side of the interchangeable user input module includes a different input device, for example, QWERTY keyboard, numeric telephone input, touch sensitive panel, scratch pad, or gaming keypad. A user would flip the interchangeable user input module depending on which feature or function was needed.
