Just having the key doesn&#x27;t automatically make it easier for you to create the new IOS. That task is significantly easier for Apple to do than for you to do. Much of security is raising level of effort for an exploit to a high enough level that it&#x27;s not worth the investment required to create it.<p>If Apple creates the new IOS for you though and all you have to do is get your hands on it then the investment required just got smaller. Any reduction in the investment required for an exploit should be <i>very</i> carefully evaluated. Saying things like &quot;This can&#x27;t possibly be used by someone else.&quot; is either disingenuous or signifies that you don&#x27;t adequately understand the issues, or you are lying to yourself. Whichever one of those that it is. It&#x27;s in Apple&#x27;s and frankly my best interest that someone highlight the truth of the situation.<p>[EDIT]: The below is more hyperbolic than I intended after a second reading. I&#x27;m leaving it since I already hit submit but I wanted to apologize for going there. :-(<p>This is like saying<p><pre><code>    Look... We&#x27;ll create a nuclear bomb but it&#x27;s okay we&#x27;re
   the only ones who will have it and nobody else is going
   to be able to get one.

Maybe you <i>can</i> guarantee that no one else get&#x27;s enough information from you to build one. However once you&#x27;ve built one the chance that someone could get the information from someone involved in your project to accelerate their creation of a nuclear bomb just increased by a non-trivial amount. And the potential risks are <i>really</i> high. Pretending otherwise would be foolish.
