The video explains no technical details and Apple has not responded; the iPhone forensics arms race escalates, and the next move is Apple's.

A leaked law-enforcement training video shows forensics vendor Magnet Forensics claiming its new GrayKey Preserve device can bypass the iPhone's 72-hour inactivity reboot.
Apple added that mechanism to iOS in November 2024: a phone that goes unlocked for 72 hours reboots automatically, making it much harder for police forensics tools to extract data. The video says the new device can hold the phone in its After First Unlock (AFU) state even across a reboot, and can switch off radios to stop remote data wipes.
The video does not explain how it works. Jiska Classen, a researcher at the Hasso Plattner Institute who reviewed a transcript, suspects Magnet found a way to manipulate the phone's clock. Apple and Magnet did not respond to requests for comment.
