Can somebody explain to me why Apple couldn&#x27;t create this exploited OS and restrict it to only run on the specific device in question?<p>If that&#x27;s the case, then they could post the source code on Github and it wouldn&#x27;t make any difference.  Modifying the code to remove the device restrictions would invalidate the signature and any iPhone would refuse to run it.  Isn&#x27;t that the whole point of code signing?<p>I&#x27;m finding it hard to see how Apple&#x27;s stance is anything other than meaningless grandstanding.  Since the vulnerability already exists, the security of similar iPhones is currently reliant on the security of Apple&#x27;s private signing key.  After releasing this exploited OS, the security of similar iPhones would still rely on the security of Apple&#x27;s private signing key.  Nothing at all would change, it&#x27;s Apple&#x27;s fault for allowing this vulnerability to be there in the first place.<p>Where am I wrong on this?  I&#x27;ve been hoping Apple would answer this question for me but instead I&#x27;ve just gotten more hyperbole.
