Help I am having issues with my Curve

I am having trouble with my curve. I have found that if I carry my curve in my pocket, or set it down outside it malfunctions. If i go to push the roller ball, it automatically pushes "*A", anytime I push the rollerball. At the same time if I type a message it comes out as jibberish. It ends up taking me 3-5 resets for the problem to fix. It is like the phone overheats, though it is not hot to touch. Has anyone else had this issue? Of course now I have had my phone over a year and it is out of warrany!!!

And I have another dumb question..my phone will not play YouTube videos, says my browser does not support it, and the browser is too old..How do I update my IE on my phone?? I cannot wait until this contract is up to get a new phone..I hate this one!!!
