I lost my iPod touch, and they are using it online, i need to track it. How?

You CAN'T -- YOU just HAVE to keep a eye out and whoever took it knew YOU had it and knew you had it in THAT locker so try to Just keep Your eye out and ALSO if yoh still HAVE YOUR case at HOME get all Your serial numbers so THAT you can. Report it stolen which you should HAVE ALREADY DONE but the CHANCE of finding it are slim but you might get lucky if You ALREADY HAVE it reported as stolen and yoh FIND out who HAS it. .ITS SOMEONE in Your p.e.class THAT got it BECAUSE They WERE watching you.

Call apple

Twitter can help. Email or call them telling your problem and asking for the location of the tweet. It will hopefully work. If not, tell your principal.

if you have a 4th generation iPod touch with iOS 4.2 or later and you have "find my iPhone/iPod" enabled on your iPod touch, you can log onto www.me.com/find on your computer and track it that way, but it has to be connected to a wifi network, which it sounds like it is because they're using it online. if you dont have it enabled, you are out of luck, because that's the only way to find it
