I have the 8330 curve and bought Greenfinder GPS for golf. Initially, it didn't work, contacted support for my carrier (US Cellular), and ran through all the tests. Turns out the GPS itself wasn't working, sent it in, got a new phone, worked perfectly for about 3 weeks, now it doesn't work again. Google Maps, BB Maps, Greenfinder< Amaze...all don't work. Can't lock in GPS signal. Any thoughts, or advise, besides sending it back in?
