5. The mobile wireless communications device of claim 1 , wherein said processor is configured to operate according to a first device indication profile while in the active mode, and to operate according to a second device indication profile while in the idle mode.
6. The mobile wireless communications device of claim 1 , further comprising an input device coupled to said processor; and wherein said processor is configured to cooperate with said input device to perform at least one device function when in the active mode, and to ignore said input device when in the idle mode.
7. The mobile wireless communications device of claim 1 , wherein the active mode is a high power consumption mode, and wherein the idle mode is a low power consumption mode.
8. The mobile wireless communications device of claim 1 , further comprising a portable housing carrying said NFC device, said magnetic sensor, and said processor.
9. The mobile wireless communications device of claim 1 , further comprising a cellular transceiver coupled to said processor and configured to perform at least one cellular communications function.
10. A mobile wireless communications device comprising:
a near field communications (NFC) device having an operating range;
a magnetic sensor having an operating range less than the operating range of said NFC device; and
a processor coupled to said NFC device and said magnetic sensor, and being switchable between an active mode and an idle mode based upon said magnetic sensor, the active mode being a high power consumption mode, the idle mode being a low power consumption mode;
said processor also configured to remain in the active mode based upon communication via said NFC device irrespective of said magnetic sensor.
11. The mobile wireless communications device of claim 10 , further comprising a display coupled to said processor; and wherein said processor is configured to activate said display when in the active mode, and to deactivate said display when in the idle mode.
