Help with restoring locked iPod touch

This is totally unrelated, but I joined so I could get some help with my 32g ipod touch. I forgot the passcode to my screen lock, and I know you can restore it but only if you sync it to the original computer. My mom bought a new comupter and sold the old one which my ipod was originally synced to. My ipod says ipod disabled at the top from trying to figure out my pass word to many times. If anyone has any solutions to this it would be greatly appreciated, as that is an expensive mistake.
