I am trying to update my iPhone 4 (4.3.3 jailbroken) to iOS 5.0 I get an error "The iPhone could not be restored. An unknown error occurred (3194)" Can anyone help me? UPDATE: I used tinyumbrella to fix my restore (after I kept getting the 3200 error when restoring in DFU mode). Then I again got the 3194 error, even though I tried to restore my hosts file to its original state. Anyways, I used a different computer to restore the phone and it is working... So this seems to be a problem with the hosts file.
