"preferred-method", LOCATION_METHOD_ACWP
"preferred-interval", LOCATION_INTERVAL_120S

my code is NOT using the gps, use the cell tower to get the position every 120 sec.

if you have others apps pulling updates from gps or in less of 120sec. the googlelatitude will be update on each pull, by design of the "gps c api". To avoid this i need migrate to qt mobile location.
