Yesterday, the Department of Justice filed a motion to vacate a hearing previously scheduled for today on whether Apple can be compelled to unlock the iPhone of Syed Farook, one of the shooters in the San Bernardino attacks.
DOJ said that since recovering Farook's phone, "the FBI has continued to research methods to gain access to the data stored on it." According to the court filing, on March 20, 2016, "an outside party demonstrated to the FBI a possible method for unlocking Farook's iPhone." Justice notes that if this method can be used on the iPhone, "it should eliminate the need for the assistance from Apple." The government will have until April 5th to test the new method.
