My iPod touch developed a strange problem today. It started not playing the vocals on any of my songs. Most of the music still plays, though, and some songs are better than others. I tried rebooting it, but I don't think it's a software issue. I found this that describes my problem almost exactly: http://forums.macosxhints.com/archive/index.php/t-77723.html Apparently one of the contacts in the headphone jack broke, so now it is only playing the difference between the left and right channels. My warranty expired a month ago (of course), so I took it apart. I don't think I can replace the headphone jack, but I found the contacts it is soldered to. Unless someone has a better solution (like if this is a common problem and there is a trick to fix it), I'll probably solder a new headphone jack on and have it sticking out the side. Maybe then Apple will replace it out of embarrassment if I show it to them!
