I think it was a good discussion, but I can't advise turning off aGPS on your grandma's ppc...
if we don't use the service, we could loose it.. feels nice to make other carriers users jealous.
;;I would recommend geeks try with aGPS off for a while though.. just depends on how concerned you are with a fast lock. me not so much, I know where I AM, just need to know WHERE to go.
