1. A mobile wireless communications device, comprising:

  • a housing;

    radio frequency (RF) circuitry comprising Bluetooth circuitry and a data and voice RF circuit that establishes communications over a public data and voice communications network, and a processor carried by the housing;

    a data store that stores instructions and data for an address book application and calendar application and priority rules that give priority between applications and address and contact information for contacting an individual over the public data and voice communications network;

    a Near Field Communications (NFC) circuit connected to the processor for communicating using an NFC communications protocol; and

    a magnetic sensor supported by the housing and connected to the processor and configured to sense a magnet of another mobile wireless communications device when the magnetic sensor is aligned with the magnet located on the other mobile wireless communications device and generate a signal to the processor, the magnetic sensor requiring a closer contact to sense the magnet of the other mobile wireless communications device than for the NFC circuit to communicate using the NFC communications protocol; and

    wherein the processor is configured to switch on the NFC circuit and activate the NFC circuit to transmit or receive Bluetooth configuration data to or from the other mobile wireless communications device using the NFC communications protocol in response to the signal, wherein the communications protocol data is related to establishing a Bluetooth communications connection between the mobile wireless communications devices, and the NFC circuit is in a lower power state when not switched on,the Bluetooth circuitry being activated after the NFC circuit receives Bluetooth configuration data related to the Bluetooth communications connection, wherein contact data for an individual to be contacted via the public data and voice communications network is received from the other mobile wireless communications device if the priority rules permit such transfer using Bluetooth communications and stored within the data store and said data and voice circuit is user actuated via the address book application to retrieve the contact data and establish voice and data communications with the individual to be contacted.
