Greenpois0n half-jailbreak with iPod 3rd Gen 8gb? ?

What firmware is your iPod Touch running? Even though the greenpois0n logo and text showed, it doesn't mean that the iPod Touch is jailbroken. Actually, I tried jailbreaking one of my friends iPhone 4s before greenpois0n was updated for iOS 4.2.1 not knowing that he was on iOS 4.2.1 and it did the same thing.
