Q: how to find my lost ipod touch

You had installed the "Find iPhone" app? With this app you can find your iPod Touch or send a sound/message. If you haven't that app, sorry but you can't do anything else. (For using this app, iPod must be conected to the internet).

Panos

what if you have the app and everything but when you try to locate your ipod for some reason the app said that the ipod is offline. and in order to online has to be connected to the internet, but if the preson who has it don't connected to the internet or doesn't used it how can I find it?

It can't be located by Find My Phone if it's powered off or not connected to the internet.
