No such program.
The iPod is in perfect conditiong, no scratches, never had a problem with it.
If you don't mind me asking, if you have never had a problem with it, why not just keep using the one you have?
Anyway, if you really want a newer one, it is easiest to sell it on eBay or Craigslist or wherever you like and apply that money to a new one. Apple would only offer you 10% if you recycled it through them.
