When I purchased my Pearl, I had some problems with the trackball. I was told to give it about a month to "break it in." Well, it's been much longer than a month and I still the same problems. I followed these directions and I'm still having the problems. The ball doesn't respond well but moves around perfectly fine. I have also done a hard reset a few times and I've also reinstalled the software. Should I just purchase a completely new trackball piece including the rollers and such? Is it worth contacting RIM to see if they will mail me one since it's still under warranty?
