how can i import my game from unity ios to ipod touch

If the game is written for IOS, it should deploy to iPod touch with no changes. The only thing you have to concern yourself with is screen resolution / aspect ratio when dealing with older generation iPods or iPads, but other than that, if you're writing for IOS, it should all just work.
