GrayKey maker claims a way around iPhone’s inactivity reboot

404 Media reports that, in a leaked video, a Magnet Forensics employee says GrayKey Preserve and Evidence Preservation Mode can keep an iPhone in its after-first-unlock state even through a reboot. Apple’s inactivity reboot occurs after 72 hours without an unlock and makes sensitive data harder for police to access. The video does not explain how the claimed workaround works.
