Research pwnage (mac) or winpwn (pc). Build a custom firmware and restore your phone in iTunes to the custom 2.0.2 unlocked firmware and you're good to go. Yes you will lose all your current apps.

ok! Guys plz help me out
I had upgraded to 2.0 using the bootneuter steps and then the bootneuter would start by itself after I restored it so it would kind of jailbreak for me... But then idk how I screwed up and went back to 1.1.4 and then I tried going back using the same exact steps but it doesn't neuter my iPhone by itself after I restore it to 2.0... It just says connect to iTunes so I had to put the 1.1.4 or else it won't work... I really need easy and guaranteed steps to go back to 2.0 plz tell me how if u can!
