    What about the small gold-colored ground pin on/near dock connector that touches the silver rim surrounding the screen?

    Oops.. I'm bad. That was for a 3G/3GS. Don't know the iPhone 4.

    The iPhone 4 one is on top of the logic board towards the very top screw in the top middle of the phone but my guess is that it's more than likely the antenna wire that runs along the dock to the lower part of the logic board by the battery isn't connected well
