6. A method for transmitting data identifying the location of a mobile communications device from the mobile communications device, the method comprising:
transmitting, from the device, a first set of data identifying the location of the device;
receiving, at the device, data comprising a second set of data identifying the location of the device after the transmission of the first set;
monitoring for a first occurring of a plurality of triggering events after the transmission of the first set, the monitoring comprising:
monitoring a time elapsed since transmitting the first set to determine whether the time elapsed exceeds a threshold time, wherein exceeding the threshold time comprises a first one of the plurality of triggering events;
monitoring a distance of the device from a location corresponding to transmission of the first set to determine whether the distance exceeds a threshold distance, wherein exceeding the threshold distance comprises a second one of the plurality of triggering events; and
monitoring, after transmission of the first set, a geographic boundary to determine whether the device crosses the geographic boundary, wherein crossing the geographic boundary comprises a second one of the plurality of triggering events; and
transmitting, to a server computer system, the second set of data upon the first occurrence of one of the plurality of triggering events, wherein the server computer system correlates the second set of data with preferences of a user regarding sharing of location data, and filters the second set of data for transmission according to the preferences.
7. The method of claim 6 , which comprises the additional step of receiving data from a server computer system which modifies the threshold time.
8. The method of claim 6 , which comprises the additional step of transmitting data to a server computer system to modify preferences for a user of the device regarding sharing of location data.
9. A method of locating a mobile communications device using a server computer system, the method comprising:
receiving, from the mobile communications device, a set of data identifying the location of the mobile communications device at a first time;
receiving, from the mobile communications device, a set of data identifying the location of the mobile communications device at a second time later than the first time the device transmitting the set of data from the second time according to a first occurring of a plurality of triggering events, the triggering events comprising:
exceeding a threshold time elapsed since the device transmitted a previous set of location data;
exceeding a threshold distance movement of the mobile communications device from a location corresponding to transmission of the previous set of location data; and
crossing a geographic boundary after transmission of the previous set of location data;
associating the set of data from the second time with a user;
correlating the set of data from the second time with preferences of the user regarding sharing of location data, the preferences stored in a database associated with the server computer system;
filtering the set of data from the second time according to the preferences; and
transmitting the filtered data.
10. The method of claim 9 , wherein the mobile communications device comprises a cellular telephone.
11. The method of claim 9 , wherein the set of data comprises GPS coordinate data.
12. The method of claim 11 , wherein the GPS coordinate data comprises GPS codes and a GPS navigation message.
13. The method of claim 9 , wherein the transmitting step comprises transmitting the filtered data to an other user.
14. The method of claim 9 , wherein:
the preferences include a specification regarding an other user among a plurality of other users who may access the set of data; and
the user specifies the other user who may access the set of data.
15. The method of claim 14 , which further comprises receiving a request from the other user to access the set of data, wherein the transmitting step comprises transmitting the filtered data to the other user.
