I also have an iPhone 4S that only charges when it's turned off and is not recognized by iTunes. I just replaced the dock port and that didn't fix the problem.

Phone broke when I tried wiring a USB cable and got the polarity backwards. From my reading, it seems possible that either the replacement dock connector was bad (cheap part from China) or the logic board needs to be replaced. Something about the logic board having a small fuse that may have been blown.

Post if you figure it out.
