1. A portable data processing device comprising:

  • a display;

    an input device;

    a proximity sensor;

    at least one processor coupled to the input device and to the display and coupled to the proximity sensor to receive data from the proximity sensor;

    a radio frequency (RF) transceiver coupled to the processor;

    a speaker coupled to the RF transceiver;

    a microphone coupled to the RF transceiver;

    a storage device coupled to the at least one processor;

    an ambient light sensor (ALS) coupled to the at least one processor, wherein the at least one processor is configured to change the power setting of the display based upon data from the ALS;

    wherein the processor is configured to determine, based upon at least the data from the proximity sensor, whether to change a state of processing of data from the input device relative to receipt of user inputs;

    wherein the input device comprises a multi-touch input panel which is integrated with the display and which is capable of determining multiple, separate concurrent touches on the multi-touch input panel and wherein the multi-touch input panel provides touch data derived from one or more touches to the multi-touch input panel and wherein when the data from the proximity sensor determines a first proximity state, the touch data is processed as an intentional user input and when the data from the proximity sensor determines a second proximity state, the touch data is either not processed as an intentional user input or is not provided by the multi-touch input panel;

    wherein the second proximity state occurs when the portable data processing device is proximate to the user'"'"'s ear;

    wherein the storage device is configured to store media for playback on the portable data processing device, and wherein the data from the proximity sensor represents at least one of a distance and a rate of change of distance; and

    wherein the at least one processor is configured to change the state of processing of the touch data from the multi-touch input panel in response to a change in the data from the proximity sensor.
