I have had my curve 8320 for at least a year now and the trackball is pretty used(black) I never thought that it would stop working. It will scroll around to everything but when I click it down there is no response. I just figured out that u can use the enter key to do the same function which is working for me now. If I bought a new trackball do you think this would help?
Also i had my phone on the sink counter and some water might have been dripped on it but everything else works and I dried out my phone....could this have caused this?
