Good point.  The thing Cook can&#x27;t say publicly is that once Apple creates FBiOS, every government around the world, especially the most oppressive regimes, will block imports of iPhones until Apple gives them a copy or they steal it from the FBI.<p>I believe the FBI is asking for FBiOS to refuse to run if the IMEI doesn&#x27;t match a compiled-in whitelist, but my understanding is that phone thieves routinely desolder a chip to change the IMEI on a stolen phone.  The FBiOS is for use when they have physical access to the phone, so I don&#x27;t believe the IMEI whitelist is a large hurdle to get over.
