The San Bernardino terrorist’s iPhone that the FBI said was critical in their investigation has, at least so far so far. Syed Farook was one of two terrorists involved in the San Bernardino shooting incident last year that left 14 people dead.

When Apple refused to comply with the court order, the FBI found an alternate hacking method and successfully hacked Farook’s iPhone.
