Finally, the JailbreakMe9 website created and maintained by Andrea Bentivegna and iCrackUriDevice is now usable again as they fixed the certification issue. The website is a wrapper to the PanguPP Jailbreak iOS application and requires absolutely no connection to any computer in order to Jailbreak the following firmware versions: iOS 9.3.3, iOS 9.3.2, iOS 9.3.1, iOS 9.3, iOS 9.2.1 and iOS 9.2 on all 64-bit devices.
The application behind this Jailbreak uses an enterprise certificate which allows the app to be installed by the phone. Keep in mind that it will search in the background for new certificates on 25PP's servers, this is normal. The Jailbreak is semi-untethered.
In this video we also got the official word from PanGU Team about the x32 devices Jailbreak and about the fully untethered Jailbreak. In the video you will see the screenshots of Pangu's official answers on reddit.
This website is in fact safer than the 25PP Chinese app method, because it does NOT ask you for entering your Apple ID nor your password anywhere on the site, so you don't have nothing to worry about. Keep in mind that Jailbreaking exposes your devices to serious threats if you don't pay attention to tweaks you install. Not all sources are trustworthy!
Thanks for Andrea Bentivegna and Tanner Marsh for creating the site, and Pangu Team for the incredible app!
