I'm not sure what you mean. Perhaps its best if I describe the error I had:
I installed 3.3.1 and used its location function. Everything worked fine and the Blue Point started moving with my position (You have to know I drove in a Bus with wifi internet access). An hour later when I started google maps again, I got my new location, but after a couple of minutes, my location was obviously not correct anymore because, the blue point showed my location on the map where I was an hour earlier. Reseting Google Maps caused it to show the correct position again for like one minute. After this minute my position on the map was again my earlier position.
After the downgrade everything works fine for me again :)
