I've been having some issues with my GPS also.
Sometimes i get it, sometimes not.
but tonight i just tried taking the battery out for 10 mins.
and then hitting the reset firewall option in the GPS options menu.
its working now.
i tested with the refresh GPS option and with Maps.
It even showed that i was connected with 4-5 satelittes in Maps as i was walking around my house. (Brooklyn, NY)
hopefully it will stay working.
