The FBI recently dropped their case against Apple after they revealed that they were able to unlock the iPhone 5C that belonged to the San Bernardino shooter with the help of the third party.
Apple does not know how the iPhone was unlocked and they may be looking to find out from the FBI how it was done.
There are other cases against Apple to have iPhones unlocked, one of the iPhones is related to a Brooklyn drug case and the justice department will reveal within the next two weeks on whether this case will continue against Apple.
If the drug case iPhone does continue against Apple, then the smartphone maker will want to find out how the FBI were unable to unlock the San Bernardino iPhone and also why this method is not being used in the drug case.
Last month a federal magistrate in Brooklyn ruled that Apple did not have to unlock the device in the drug case, although the Justice Department appealed this to the district court.
If the case does go ahead against Apple, then they may be able to use what happened in the FBI case to find out how the iPhone 5C was unlocked, Apple would obviously want to fix this method on their iPhones as it could be used by criminal to access data on iPhones.
