    When does this error message appear in the process?

    You're getting that because you're naughty and Jailbroke your phone.


    When you update your IOS it checks the firmware with Apple's signing server gs.apple.com


    Check your HOSTS file in (Open in Notepad/TextEdit)


    Windows -> c:\windows\system32\drivers\etc\hosts

    Mac -> /etc/Hosts


    Add the following line to the bottom of the file



    Save the Hosts file and restart the PC/Mac. Should fix it.


    Reason that its doing that is because it errors with Apple's signing server (Moreso it rejects you because your running hacked firmware). Changing the above to Cydia's signing server will allow it to update properly.


    Once you've finished the update - make sure you delete that line back out of your HOSTS file and reboot again.

    I just bought my Iphone 4 from apple a few weks ago and it doesn't let me upgrade either. it gets the same error. how can i get a hacked phone when it is new from apple?

    You can't. I'm guessing you are on a PC and you are using antivirus/antispyware software. Disable all of it and try again.

    @tadct the phone itself might be new from Apple but 3194 is a signing error on Firmware updates from SHSH Blobs. If you have previously had another iPhone (3GS) and have jailbroken that it might have still patched your HOSTS file and it hasn't been changed from that Jailbreak.. Just check that file first and foremost to make sure its pointing at the right place first
