Handheld electronic device, user interface and method employing an input wheel disposed at about a 45 degree angle

A user interface for a handheld electronic device, said user interface comprising:

• an input apparatus comprising a single rotational axis and a wheel adapted to rotate about said single rotational axis in a first rotational direction and an opposite second rotational direction;
• and
• a display adapted to alternatively display a first list and a second list, said first list including a plurality of first objects disposed in a first longitudinal direction, said second list including a plurality of second objects disposed in a different second longitudinal direction,
• wherein said single rotational axis is disposed at an angle of about 45 degrees with respect to said first longitudinal direction and to said second longitudinal direction, and
• wherein said display is adapted to scroll said first objects or said second objects responsive to rotation of said wheel in the first rotational direction or the opposite second rotational direction.
