how to unlock ipod touch without the password

 If you use the following steps, you will lose all information that is currently stored on the iPod. You will lose all of the music, pictures, videos and applications stored on the iPod Touch. Also, be sure you have iTunes installed on your computer before you try to reset it.

First, you should see a screen asking you to enter the passcode. While the iPod is locked on this screen, plug it into your computer.

When you plug the iPod into the computer, iTunes should open.  iTunes will then give you a message telling you it cannot open the iPod because it requires a password.  Keep the iPod plugged in. Then click Cancel and close iTunes.

The iPod should be plugged into the computer and iTunes should be closed.  Now you will need to hold the Power Sleep/Wake button (on top) and the Home button together for about 20 to 25 seconds. Hold the two buttons together until the iPod resets and shows a screen with a USB plug and an iTunes logo.

When you see this USB & iTunes screen, you will need to open iTunes.

You will then see a screen in iTunes telling you it detected an iPod in recovery mode. Click OK.

Then you will see the screen in iTunes where you can restore the iPod. Click the Restore button.

After you click the Restore button in iTunes, leave the iPod plugged into the computer until it is done restoring! Do not unplug the iPod. Do not push any of the buttons. Do not touch the screen.  Let it restore in peace..

When the iPod is done downloading the latest software and it is done restoring, you will see the screen where you can sync the iPod with music, videos, applications, and the photos you choose.
