After jailbreak on 1..1.1 and installing the oktoprep I went to the iTunes to update to 1.1.2 and it showed an error message. Than i tried to restore to 1.1.2 to check if the problem was the firmware i downloaded and the same error showed up. I downloaded the 1.1.2 firmware from another link and the same error continue to appear. I'm usin mac. Does anybody knows anyting about that? Pleeease! i wanna get my 1.1.3 jailbroken, but i cant even have the 1.1.2 Thanks!
