  • disabling the GPS circuitry via a GPS enabling block of the mobile wireless device responsive to a user selection to disable the GPS circuitry, wherein disabling includes removing power from the GPS circuitry, and wherein the mobile wireless device otherwise remains operational, the disabling performed responsive to a user input to disable the GPS circuitry to prevent sending location data without consent of a user of the mobile wireless device;

    detecting, via detect/control circuitry disposed in the mobile wireless device, an input at a keypad of the mobile wireless device from a user of the mobile wireless device, the input representing an emergency call; and

    enabling the GPS circuitry despite prior disablement of the GPS circuitry by the GPS enabling block, by providing power to the GPS circuitry in spite of the user selection, performed by the detect/control circuitry, and performed upon detection of the input representing the emergency call.
