Rotating user interface

A handheld electronic device comprising:

• a first housing portion;
• a rotatable user interface coupled to said first housing portion wherein said rotatable user interface rotates about a first axis, and
• wherein said rotatable user interface is a circular rotating user interface, and wherein said circular rotating user interface encompasses at least a portion of said configurable user interface;
• a rotation sensor coupled to said rotatable user interface;
• a configurable user interface wherein at least a portion thereof is a configurable user interface movable portion, movable relative to said housing portion and said rotatable user interface said configurable user interface movable portion comprising a plurality of keys,
• wherein at least said configurable user interface movable portion of said configurable user interface is moveable about said first axis;
• a controller coupled to said configurable user interface and said rotation sensor, operable to receive signals from said configurable user interface, said rotation sensor and to detect incremental movement of said rotatable user interface in a first direction of rotation and a second direction of rotation opposite said first direction of rotation;
• and
• a second user interface coupled to said controller outputs a first function proportional to the amount of incremental change in rotation and relative to the first direction of rotation of said rotatable user interface, and outputs a second function proportional to the amount of incremental change in rotation and relative to the direction of rotation of said rotatable user interface.
