The government writes that there is no reason to believe that the code for Govt. OS "will ever leave Apple’s possession. Nothing in the Order requires Apple to provide that code to the government or to explain to the government how it works. Far from being a master key, the software simply disarms a booby trap affixed to one door."
The filing also refutes Apple's claim that it could have backed up data to iCloud via a Wi-Fi network to give the DOJ what it wants, had the government not changed the Apple iCloud password belonging to the device. The new DOJ filing says that it was Farook himself who had made the change to the password three days after the final back up was completed. The FBI also said that when it received the phone, it was powered down which would have made it impossible to connect to Wi-Fi before punching in the passcode.
Apple general counsel Bruce Sewell called the filing hostile, adding that "I don't think I've ever seen a legal brief more intended to smear the other side." Talking to the media, Sewell added "To do this in a brief just shows the desperation that the Department of Justice is now feeling."
Both sides will present their arguments before the judge on March 22nd, the day after Apple is holding a media event. During that event, we should see the company unveil the 4-inch Apple iPhone SE, the 9.7-inch iPad Pro and a refreshed Apple Watch.
