Thanks for this. This site rocks!

Yeah, as you pointed out, I'm worried it might be the contact in the phone itself. I look at the trackball assembly and it seems like it is intact and that it is just a thin sliver of metal that the ball pushes down to a contact on the phone's circuit board.

I'll try swapping it out tonight and report back.
