My friends phone had a problem where it would not syn to active sync but would charge. I tried everything, hard reset, taking the bat out, different cables, computers nothing worked. We brought it to sprint repair store and they said they cleaned the port out with a wire brush using a little bit of alcohol. I would make sure to take your bat out and have the phone off obviously while you are cleaning. He also said to make sure you take canned air to the port to make sure it's dry right after you are done brushing. Gives this a shot, similar issues hopefully that will take care of it. Good luck
