iPod Touch Headphone Jack was All Jacked Up; Jacked in a New Jack
Quality Apple workmanship [cough] caused my headphone jack to stop outputting sound. I was forced to ride around in the car with the speaker on high while holding the Touch near my ear.
Surprisingly straightforward. After opening up the guts, It was just a matter of undoing a single screw and popping the connector off the logic board. Now, the reassembly, on the other hand, was much tougher than I expected.
I've seen snowflakes bigger than the screws that hold this thing together. Also, reattaching the LCD cable to the logic board (the last step before re-sealing your Touch) is much more challenging that the guide would have you believe. Keep an extra supply of patience on hand for this step.
