Ear phone jack operates intermittantly.

Definitely needs a new headphone jack. This is possible to replace yourself, but it is tricky. I don't think iFixit carries this part, but I know you can get the part from eBay for about $5-$10. What generation of iPod Touch do you have? For the first gen iPod Touch, you just take off the backplate and unscrew a couple screws around the headphone jack before unsoldering the 4 points that hold it on. Carefully remove the old and stick the new one in, and resolder. The 2nd/3rd gen iPod touches are a little different (you have to take them apart a bit more) but can still be done.
