Heh.  Open firmware would not solve this issue.  If the firmware were open, the FBI would have already broken into the device.  Apple&#x27;s signing key (or, for the paranoid, the government&#x27;s unwillingness to admit that they have obtained it through espionage) is primarily what is keeping the FBi&#x27;s fingers out of the cookie jar.<p>A better question is how to further lock the phone down in future updates so that Apple can&#x27;t comply even if they were compelled to, something Apple engineers are no doubt looking into right now.  The optimal way would be to require a device to be unlocked to update the firmware, which would require the PIN, which Apple would not have.
