I have a t-mobile g1 running OTA 1.5 cupcake firmware. Not rooted or unlocked. I'm not sure if this is something possibly related to cupcake or not since I haven't tried this since well before the update. When I use GPS in the maps application my on map indicator would follow me as I drove down the road so I could keep up with where I was on the map. Now GPS will fix my location and set my indicator but not move my map indicator down the road with me. Any ideas?
