I thought that the problem originated from the headphone socket because my headphones are new and whenever I try to plug the headphone jack ALL THE WAY IN, only the other ear piece emits the sound. But when I tried to plug the jack just HALF-WAY, the sound comes from both pieces. I've tried doing this several times and it keeps on doing that. What should I do to make the socket work properly again? If I open up the device, would it erase everything that is in the ipod? Please help me. Thank you.
