agreed, i tried it with the dialer in froyo and nothing.
+1 I have had this problem also since I went to 2.2. I was able to get into these settings on 2.1, but w/2.2.... nothing.

This is nuts. I can't use Sprint or Google Navigation, but everything else that uses GPS seems to work fine. I did exactly what the original post said to do, and it was fine for one day, then it stopped working.
Any ideas?
I downloaded a GPS Test app. When wifi/4G is on, it says there are no satellites in view or in use. When I go strictly 3G, all of the sudden I have 5 or 7 satellites. When I turn 4G back on, all I get is a "waiting for location" message in Google Navigation that doesn't seem to go away.
