Up to that point, if a government needed Apple’s help unlocking an iPhone, they had to physically fly to Cupertino and bring the phone into a secure sensitive compartmented information facility (SCIF), where a trusted Apple engineer unlocked it. The trips could be comical. In one case, a foreign government sent an iPhone, along with a government minder, by chartered jet to Cupertino, only to get into the SCIF and learn from Apple’s engineer that the owner had never even bothered to set up a passcode.
