Hansel, there is a previous answer of mine that you might want to explore. I bet one of the pins inside your jack is bend and not making proper contact. You may get it re-adjusted by opening your ipod and taking a look at the jack itself but I do not think that you can get to the contacts. So I suppose your best bet would to replace it since you have it apart anyway. The part is available here http://www.digiexpress.us/iPod-Touch-2G3G-Headphone-Jack_p_178.html good luck to you. See if this will fix your issue. Good Luck
