1. A system that initiates, enables, disables, or restores cellphone operations when said cellphone is in a zone, comprising:

  • (a) a zone, which is a contiguous geographical area where courteous cellphones may be operable, such as an auditorium,(b) data describing said zone, comprising bits to initiate, enable, disable or restore cellphone operations in said zone,(c) said zone being coextensive with a three-dimensional concave polygon, said polygon having a plurality of corners, said corner having GPSS coordinates,(d) a courtesy signal transmitter transmitting courtesy signals to courtesy signal receivers in said courteous cellphones that are within said transmitter'"'"'s cover, a transmitter'"'"'s cover being a largest surface of a contiguous volume in which anywhere in the volume said courtesy signal transmitted from said courtesy signal transmitter is of sufficient power to be received and decoded, with acceptable probability, in a courtesy signal receiver disposed in said courteous cellphone,(e) placing courtesy signal transmitters such that all of said polygon'"'"'s interior be under the cover of at least one courtesy signal transmitter, but such that no two said courtesy signal transmitter signals interfering with each other,(f) a cellphone comprising components;

    (i) a transceiver that communicates with a cellphone tower to communicate voice and data signals to or from other cellphones, said transceiver not communicating any said data describing said zones, corners or bits,(ii) a microphone that inputs audio signals,(iii) a speaker that outputs audio signals,(iv) a keyboard wherein telephone numbers can be dialed and data can be entered,(v) a display where at least said telephone number being dialed can be displayed,(vi) a ringer that outputs a ring tone, and(vii) (optionally) a camera where a picture or a video can be taken,(g) a GPSS system disposed within and coupled to said cellphone that outputs coordinates of said cellphone'"'"'s current location,(h) a cellphone memory, disposed within said cellphone and storing, at least in part, said polygon'"'"'s corner'"'"'s coordinates and said of polygon'"'"'s bits, said stored data not including said cellphone users'"'"'personal data, nor data being provided in response to said cellphone user having an accident, and said stored data not being any part of a message'"'"'s zone address,(j) a processor that initializes said memory with data describing said zones, polygons, polygon'"'"'s corners and bits in the zone, and then repeatedly executes forever a single loop program,(k) a single pass of said single loop program that repeatedly reads each said zone'"'"'s data, read one zone at a time from said memory, to compare it to the cellphone location obtained from said GPS system,wherein, if said cellphone is in said zone, said processor, responsive to said zones'"'"' data bits, initiates, enables, disables or restores operations in said cellphone'"'"'s components.
