I just got my curve last week and have been using it like crazy. I can tell that the trackball is already getting dirty. What is the best and safest way to clean it?
I believe there are ways to take the trackball out (I personally wouldn't try this as I'm a wimp and would be scared to death of breaking my BB) and that is in the FAQ forum I think.
Personally I think I'll clean mine by getting a wet wipe and then just rolling the trackball around, won't get it perfect but clean enough. I say this because the trackball seems exactly like the little ball in the Apple Mighty Mouse... and that's how they advise cleaning it.
