Apple: 'We do not compromise', but the FBI does himself and finds out how to hack iPhone

It's a constant give and take between the Apple and the FBI. Just last night Tim Cook proposed to us a monologue on the importance of safety and the decision of the company not to compromise even under explicit demand from government agencies. A few hours from the reflection of Apple CEO gets a US Department of Justice document asking the courts to suspend the hearing for tomorrow with Apple regarding the massacre in San Bernardino.
Apparently the FBI will use "alternative methods" to penetrate the aggressor smartphone, Rizwan Syed Farook, and no longer need the help of the company. Here's what it said in a document filed with the courts by the DOJ:
Sunday, March 20, 2016 a third-party user has demonstrated the FBI a possible method to unlock the iPhone Farook. Further tests are needed to determine whether it is a method that does not affect the data on the terminal. If the method was practicable it should eliminate the need for assistance by Apple established in the All Writs Act Order in this case.
This does not mean that discussions are completely finished between the two companies. The Department of Justice proposes the presentation of a report on these tests to take place on April 5. If the procedure goes through it is likely that Apple and the FBI will return later in court to discuss once again the release of the terminal. It probably will remain anonymous, "the third-party user" had offered to unlock the iPhone 5C Farook who, for all we know at present, could be either an individual who a company.
Apple and Tim Cook have struggled over the last month to prevent government agencies could require technology companies to develop what is called GovtOS. This is, in short, an operating system in which the experts can access at any time to integrated data at the request of the authorities, but at the same time could leave open backdoor available for all potential external aggressors.
Apple has spoken several times of the argument, and I also spoke yesterday during the presentation event of its latest devices, with Tim Cook who has also appeared on ABC News to explain the company's position. FBI and DOJ believe that it is of a single iPhone tampering to retrieve information that could lead directly to ISIS members. But for Apple, the inclusion of a voluntary backdoor would represent a betrayal of its customers.
