How to delete everything on an iPod Touch? I would like to give my iPod touch as a gift to someone I know, but I want to be sure that there is nothing left on it to avoid giving data with it...

How do I clean the iPod ?
Fully charge the iPod Touch
Go to the Settings menu. Scroll down until you see the "General" settings, and hit that, then scan to the very bottom, where you'll see a mini-menu titled "Reset." Press this. This will bring up a few different options, but the one you want is "Erase All Content and Settings." (Settings / General / Reset / Erase all )


you can see full detailed here.

Also you can use itunes, and go to the restore feature. This will take your ipod back to factory default.
