We&#x27;re not saying it&#x27;s just the signing key. We&#x27;re saying it&#x27;s trivial to make those changes.<p>For the record, I made this claim before I saw anything from saurik. The changes are very minor, just disable erasure and the delay, plus something to allow remote password attempts.<p>Re &quot;OS being released&quot; that&#x27;s not something that matters, because the OS is useless without the key. The only risk is compromise of the signing key, and that&#x27;s the same as any iOS update.<p>Do you have any other justification for your belief other than trusting Tim Cook?<p>I&#x27;m not claiming he&#x27;s more knowledgeable, but that Cook lied. This may just be poor phrasing or dumbing down on Cook&#x27;s part, but the implication is wrong.
