I jailbroke my 4th gen Itouch on iOS 4.2.1 with the latest green poison and it works perfectly and my friend with a 3rd gen Itouch on iOS 4.2.1 wants his jailbroken to so I tryed it with the same green pision as mine and it keeps saying jailbreak failed click here to try again I tryed this like 3-4 times with the same outcome is it just because I was using a different computer or is it green poision if so what will work ps I know it's greenpoisi0n but that would have taken for ever to wright
