Bravo DP...

If you advertise that you found it just make sure you don't say what it is.
You could just say it's an mp3 player without saying what kind! Then the person has to guess make, model, color, engraving... etc...
Also, an iPod can only be synchronised with one pc at a time, unless you use Anapod, but thats another story, so it would be easy to tell if the person is the owner ;)

good luck in reserving your spot in the heavens :P
