A handheld device that intuitively switches operating modes based upon the device position. Each operating mode is associated with a particular device position. If the device recognizes a change in its physical orientation it may trigger a change in its operating mode to correspond to the new orientation. The operating modes may be a speakerphone mode and handset mode associated with a voice call. The device may enter speakerphone mode when held substantially flat and may switch to handset mode when the device is lifted up and tilted to the user's ear. An orientation sensor contained within the device may provide the orientation data based upon which the device selects its operating mode.
