Some of you know my water damage woes. Anyways, the phone is dried out and miraculously, working perfectly fine. You know there's an "except" here. My ringer volume buttons don't work and I can't hear keyboard clicks, etc. I did some research and it said it's an issue with the docking port. I tried cleaning it with a toothbrush and the ringer buttons work for about 2 seconds after each cleaning but then stop again. Is it fairly easy/inexpensive to have the dock port replaced? Any other advice...?
