I've got my second gen. ipod touch here, and a bit of a problem. I've figured out that the problem is purely the ipod, not wires or computer or outlet or anything. I think there may be something physically wrong with the port, but visabley wrong. This is random problem,as it stopped sensing the plug 30 minutes after I saw it working. This never happened to it before. I've tried basic troubeshooting, searching for lint in the jack, etc. At this point, i've got no idea. Help?
