Law enforcement agencies under the guidance of the United States government may have gone to almost every single length possible to gain access to one of Apple's iPhones, but it looks as though that unwavering pursuit is yet to prove fruitful for the FBI. After unsuccessfully attempting to force Apple to unlock an iPhone 5c used in the San Bernardino shooting last year, the FBI allegedly enlisted the help of hackers familiar with a flaw in the iOS software to gain access to the data within. According to a new report that access has so far failed to produce any findings that are noteworthy or relevant to the case.
