Ipod Nano Question?

My son got an Ipod Nano for his birthday and put a lock on it and now doesnt know what code he put in. Anyone know what he can do to open it again?
Thanks

Dont know if this will help you:

Normally, if you can connect iPod nano to the computer it’s authorized to work with,
iPod nano automatically unlocks. If the computer authorized to work with iPod nano is
unavailable, you can connect iPod nano to another computer and use iTunes to restore
iPod software. See the next section for more information.
If you want to change the screen lock combination and you can’t remember the
current combination, you must restore the iPod software and then set a new
combination.

If that doesnt work then if you ring apple ipod on 0844 2090611 they may be able to help, i rang them this morning about my ipod and they very helpfull.

I will try that tomorrow thank you so much, you may of saved a little boys life, as he wasnt my favourite boy after doing this.

Did you have any luck in unlocking ipod?

Will try it tonight when he's back in. I will let you know
