I've had instances where it was just "stuck" as well. GPS Status would indicate that it could find plenty of satellites but that it couldn't get a lock on any of them.This happens in a couple of situations. If you have GPS turned off or it hasn't yet located a sufficient number of satellites to locate you specifically, it will use either the nearest cell tower (with a big blue circle) or the GPS info it has managed to snag to give a less than precise location (again with the blue circle.)
