My cousin completely messed up his iphone. I dont know what he did. But in any case, he gave the iphone to me to get it repaired. It was in recovery mode. So I, not really knowing what to do, gave ziphone a try. Somehow ziphone worked. But there's a problem. The iphone now has 1.1.1 firmware with 04.04.05_G baseband. Also the installer.app is not installed. Now I wish to upgrade it to 1.1.4 and install the Installer.app on it. Do I simply upgrade this iPhone to 1.1.4 via itunes and then unlock it with ziphone. Or do i need to take some percautionary measures like oktoprep first and then upgrade. Can somebody please point me to the right guide to do it. All I m worried bout is that the firmware and baseband do not match.
