ipod touch locked all the way cant get in at all
You can erase your iPod in recovery mode using iTunes. This process will wipe out everything on the iPod including passwords. Here's a link to Apple's instructions.

Scroll down to a little over half way to the heading: "Erase your device with recovery mode."

I had to do this with a used iPod I bought a few weeks ago.
