iPod Touch 2G MB 4.2.1 Jailbreak?

[Ewan Smith]

Is it possible to jailbreak it? I tried using greenpois0n but it keeps on saying "Failed " and my iPod is stuck in DFU, I can get out of it though.

It is possible to jailbreak your device and there are lost of different ways to do it.
In your situation you maybe made a mistake going into DFU Mode. Just try it again or use another jailbreak like Sn0wbreeze.
