I have unlocked a few iphones all were 4 or 8 gig iphones. i unlicked 1.1.4 ,2.0.0 2.0.1 ,2.0.2 and all went fine. I have a brand new apple iphone 16gig 2g . i tried unlocking it with winpwn, libirty , pwnage and none have worked. When i use winpwn 18.104.22.168 i get a 1604 error in itunes. When i try and use libirty i cant clock on go for it , its grayed out When i try and use winpwn2.5 it creates the custom firmware puts the phone in DFU then error and it closes winpwn.
