Folding wireless communication devices (100, 700) comprise first parts (102, 1002) that are rotatably coupled to second parts (104, 1104). The first parts (102, 1002) can be moved from first positions in which the first parts (102, 1002) overlie the second parts (104, 1104) to second positions in wh

Folding wireless communication devices (100, 700) comprise first parts (102, 1002) that are rotatably coupled to second parts (104, 1104). The first parts (102, 1002) can be moved from first positions in which the first parts (102, 1002) overlie the second parts (104, 1104) to second positions in which the first parts (102, 1002) extend upward away from the second parts (104, 1104). The first parts (102, 1002) comprise one or more buttons (302, 304, 306, 308 1010, 1012), e.g., a pair of directional buttons, such as "UP" and "DOWN" control buttons (302, 304, 1010, 1012). Hardware and/or software is used to change the function of the buttons (302, 304, 306, 308 1010, 1012) depending on the position of the first parts (102, 1002).

What is claimed is: 1. A handheld communication device comprising: a lower part; a hinge coupled to said lower part; a flip coupled to said lower part by said hinge, wherein said flip can be rotated about said hinge from a first position in which said flip overlies said lower part to a second position in which said flip extends upward away from said lower part, said flip comprising one or more buttons; a sensor adapted to detect whether said flip is in said first position; a controller electrically coupled to said one or more buttons, and to said sensor; wherein said controller is configured to read an output of said sensor, and process input from said one or more buttons in a manner that depends on the output of said sensor; and wherein said one or more buttons comprise a pair of buttons including a first button, and a second button that is located above said first button when said handheld communication device is held upright, and said flip is in said first position; and said controller is configured to interpret a first actuation signal from said first button as a "DOWN" command, and a second actuation signal from said second button as an "UP" command, when said output of said sensor indicates that said flip is in said first position; and said controller is configured to interpret said first actuation signal from said first button as the "UP" command, and said second actuation signal from said second button as the "DOWN" command, when said output of said sensor indicates that said flip is not in said first position. 2. The handheld communication device according to claim 1 further comprising: an audio output system coupled to said controller, wherein said audio output system is responsive to said controller to adjust a volume of audio output by said audio output system; and when said controller is in one or more states of operation, said controller is configured to interpret said "UP" command and said "DOWN" command as audio volume control commands, and adjust the volume of audio output by said audio output system up and down in response to said "UP" command and "DOWN" command respectively, whereby, with said handheld communication device held upright regardless of whether the flip is in the first position or the second position, whichever of the first and second buttons is on top will serve to increase volume, and whichever of the first and second buttons is on bottom will serve to decrease volume. 3. The handheld communication device according to claim 1 further comprising: a first display on a first surface of said flip that faces said lower part when said flip is in said first position; and wherein said controller is configured to display a first vertical arrangement of selections on said first display, when said flip is in said second position; and when said first vertical arrangement of selections is displayed on said first display, said controller is configured to interpret said "UP" command and said "DOWN" command as vertical navigation commands for controlling position in said first vertical arrangement of selections. 4. The handheld communication device according to claim 3 wherein: said first vertical arrangement of selections comprises a control menu. 5. The handheld communication device according to claim 3 wherein: said first vertical arrangement comprises a list. 6. The handheld communication device according to claim 3 further comprising: a second display located on a second surface of said flip opposite said first surface; wherein said controller is configured to display a second vertical arrangement of selections on said second display; and when said second vertical arrangement of selections is displayed on said second display, said controller is configured to interpret said "UP" command and said "DOWN" command as vertical navigation commands for controlling position in said second vertical arrangement of selections.
