When I had my iPod Touch jailbroken before, my lock button and up volume button began doing the same thing. When I locked it, I would also increase the volume, and when I increased the volume, I would also lock it. I decided I would try restoring the original firmware to remedy the problem, but found that I was unable to do this. It would just not work. I'm not sure why this was. I gave up, and several months later, tried restoring the firmware again. It worked perfectly, and I have not had any problems since. Now, I am considering jailbreaking it again...but I'm leery because of what happened. Would the volume button/lock button confusion of had anything to do with jailbreaking? Was the trouble with restoring due to the lock button/volume button issue? I just don't want to have to worry. If something goes wrong, I want to be able to restore without trouble. Any insight into this would be great guys. Thanks a lot.
