You can lock your iPod Touch by simply pressing the long slim button (the "sleep/wake" button) at the top of the iPod. This will shut your screen off. If the sleep/wake or home buttons are pressed, you will see a screen with a lock symbol on the top bar. Slide the bar and enter your passcode if required to unlock.
