I dont know what is wrong with my computer. I have 4 3GS's and 3 3Gs.
I have tried to restore iPhones to stock 4.2.1 firmware and it returns error 1600.
I have tried to restore iPhones to Pwnage cooked 4.1 and 4.2.1 and it returns error 1600.
Is something wrong with my computer?? I have tried EVERYTHING I HAVE FOUND. Its been 5 days by now that I am trying to find a way to restore iPhones. I remember erasing the gs.apple.com lines on the Hosts archive a few days back. May that be the issue? Im going insane already! PLEASE SOMEBODY HELP ME!
