G1 Accelerometer problems

I've been having a problem with my G1's accelerometer not registering movement in all directions, currently with it not wanting to switch between landscape and portrait screen modes automatically (and not alot of apps support manually changing it). Has anyone had this issue on their G1 before, or more importantly figured out a way to fix it besides wiping the entire thing?

Are you still having issues with this? I have found my Accelerometer only switch to one side, the left side, but if I Tilt it to the right side it will not turn, nor will it turn to the up side down either. I believe this is just the way the software it designed, and I don't believe this is a problem.
