Hi, The Gears Geolocation API uses a variety of methods to attempt to get a position fix. These include IP and WiFi on desktop and IP, WiFi, Cell ID and GPS on mobile devices. Gears will return the best position from all of the available methods. You can't 'force' Gears to use only Cell ID data, but you can pass options to the API calls in order to enable or disable the use of GPS. See http://code.google.com/apis/gears/api_geolocation.html.
Can you explain why you want to 'force' the use of Cell ID for obtaining a position fix? Steve
