Change Phone Profiles Based on Location

Another Psiloc program for Series 60 devices, called miniGPS (http://www.psiloc.com/index.html?id=155), allows you to change profiles automatically depending on your (approximate) location. The Global System for Mobile communications (GSM) cellular network is serviced by a network of base stations. The area covered by each base station is known as a cell, which can be anywhere from 100 square meters in a crowded city to 3 square miles in the countryside. Using the area ID and the cell ID of the current base station, miniGPS determines the approximate position of the phone. For instance, if your office and home are more than 100 meters away from each other, they are likely to be serviced by base stations with different cell IDs.
