Once fixed, iPhones will no longer be vulnerable to intrusion via the Lightning port used both to transfer data and to charge iPhones. The port will still function after the update, but will shut off data an hour after a phone is locked if the correct password isn't entered.

The current flaw has provided a point of entry for authorities across the U.S. since the FBI paid an unidentified third party in 2016 to unlock an iPhone used by a mass killer in the San Bernardino shooting a few months earlier. The FBI sought outside help after Apple rebuffed the agency's efforts to make the company create a security backdoor into iPhone technology.
