Here's How the FBI Screwed itself
But the Twist lies here:
The Apple ID passcode linked to the iPhone belonging to one of the San Bernardino terrorists was changed less than 24 hours after the government took possession of the device, senior Apple executives said Friday. If that hadn't happened, Apple said, a backup of the information the government was seeking may have been accessible…
The executives said the company had been in regular discussions with the government since early January, and that it proposed four different ways to recover the information the government is interested in without building a back door. One of those methods would have involved connecting the phone to a known wifi network.
