Just a few days ago we updated iOS Forensic Toolkit with iOS 10 support. At that time, no jailbreak was available for iOS 10.2. As a consequence, physical acquisition was impossible.
A working jailbreak materialized much sooner than we could’ve hoped. Luca Todesco released a working Yalu102 jailbreak, allowing enthusiasts to mod their devices and enabling forensic experts perform physical acquisition of select iOS devices.
