A few months ago on my 3G, I tried switching my silent switch over and it wouldn't stay silent. The switch does go fully to the left side, but it doesn't do the typical vibrate and show the silent graphic on the phone. BUT if I ever so slightly nudge it to the left it does go to silent but there is no way to keep it in place. It is almost as if there is something in the way or maybe there is a short? My warranty is no longer valid, but the phone is in perfect condition, has been cased. It makes no sense. Anybody have any advice, because I would like to sell the phone soon but obviously do not want to sell it without the silent working. I guess I could go to a cell phone repair shop but they charge a $30 diagnosis fee and then apply that to the repair. I do not want to get screwed. Anybody have ANY advice or experience with the switch conking out on them. Any home remedies?
