My headphone jack busted. I can't commute without my iPod!
The repair went without a hitch. I had seen a video on YouTube about how to replace the jack, so when I got in there, it was straight forward. Took maybe 20-30 minutes.
I definitely recommend you get the plastic opening tools. Also, make sure you use a magnetic screwdriver. The screws holding the headphone jack are tiny, any it's difficult to get them in place by hand.
