What size/generation iPod is it?

So unless you know someone who's good at fixing them.... buy a new one.

I'm NOT an employee of Best Buy, or Geek Squad, though I did work as an Agent for a year. None of my posts are to be taken as the official stance that Best Buy will take on your situation. My advice is just that, advice.
Unfortunately, that's the bad luck of any electronic, there's going to be bad Apples... wait that's a horrible pun.
