Answer to: iPhone 4 won't charge!Using a set of tweezers, I cleaned the dock socket and it still didn't charge. I replaced the dock socket and now I have a new battery and a socket for Australian$70. My phone is now back in action.
Answer to: iPhone 4 won't charge!My iphone 4 had the same problem. It says that it is connected and it can transfer data but it doesnt charge. I had the battery replaced and therefore I was able to retrieve photos etc which is good. Even when it is attached to the wall socket it doesnt do anything. I think it must be the dock socket. Ill replace that and see if that fixes it.
