Hi all, I am trying to winpwn my iPhone to 2.0. I downgraded to 1.1.4 and dled winpwn 2.0. I found some 2.0 firmware and attempted to use it for the winpwn. It says "unknown file" however and doesn't go any farther. I attempted to shift+restore in iTunes and got the 1600 error. Help me finish this please.
