Hey iv123, Apple will not help, and having the serial number will help you ID your iPod should someone turn it in to a lost and found or the police, but that's about it. As Alan has stated you will need to go physically look for it. Good luck. Also, if you haven't already done so, report it lost / stolen to the police, they will do little, but if someone turns it in you may get a call. You should check with lost and founds also if lost in a public area. If you set up an iCloud account you can disable the iPod so if a thief attempts to use your iPod on line, it be wiped. Also, you should disconnect from this iPod, change all passwords / account information associated with this iPod to limit a thief's access to your information. Hope this helps. Cheers.
