How do you un jailbreak a ipod touch?

Is there anyway to un-jailbreak my ipod touch?

• I jailbroke my ipod, and it's been nothing but problems ever since. It won't work now, so I talked to Apple over the phone, and they couldn't help. I've tried restoring, but it gets halfway through the restoration process then freezes. Now I have to take it to the closest Apple store (which is over an hours drive away from my house) to get it repaired. I'm thinking that if I can remove the jailbreak software, it might help. Can anyone help?

• Answer:

  The only way to un-jailbreak it is to restore it. Try to delete all of your apps off of it and then try to restore it. If it doesn't work then take it to apple but know that you've voided your warranty by jailbreaking it so apple may not be much of a help. Hope it helps.
