Jailbreaking an Old iPod running 2.2.1!?!

[domefavor95]

Ok, so I got a iPod here. I need to get SHSH for it that way I could upgrade it to 4.0. Its not my iPod. My friend gave it to me to upgrade only to 4.0. I was wondering if anyone could give me a old tutorial to jailbreak it. It's a 8GB and 2nd Gen. I need Cydia that way I can save the SHSH because TinyUmbrella isn't working for me. Can you please help?

Yes it has to be 4.0

The 4.0 shsh is long gone. Why do u need it on 4.0 tho?

The 2G iPods can only go up to 4.2.1. Just jailbreak it with green poison.
