I bought a waterdamaged iphone off of ebay that would not turn on or be charge/connect to itunes. I took the phone apart, and followed this youtube video. http://www.youtube.com/watch?v=zLoFdqNf3... I also replaced the battery which is like $6 or less on amazon or ebay. After doing this, the phone turned on, everything functioned perfect - camera, touch screen, vibrate, speaker, etc - except my dock connector. Basically my phone operates perfect, but the dock connector for charging/connecting doesn't work, even after I replaced the dock connector. I've heard others having luck and everything including the dock connector works after doing this. Still working on this problem haha. Anyway good luck!
