I just updated software for my ipod video and now the left side of headphones don't work. What's going on? The ipod worked perfectly yesterday, and suddenly it just breaks on its own? I can get sound cracking in and out if I move the headphone jack around but that's it. I also tried 2 different headphones. I tried resetting the ipod to factory settings, too, which was useless. Any tips would be great... is it possible installing the new software did this? I can't sort out for the life of me how.
