Yes, the precedent is the key thing here.<p>Let&#x27;s say that Apple crafted an update that does what the FBI wants. That in itself wouldn&#x27;t put other iPhones at risk, as long as a signed copy of that malicious update didn&#x27;t leave Apple&#x27;s custody. The FBI hasn&#x27;t even asked for that. They say that Apple could do all the work in house. Furthermore, it&#x27;s unlikely that this malicious update would work on newer iPhones.<p>But the precedent would be established.
