Hacker Luca Todesco has announced a webkit based iOS 9.3.X pangu loader
that addresses certificate frustrations with Pangu's latest jailbreak.
Basically, the exploit lets you reactivate the Pangu jailbreak by just navigating to https://jbme.qwertyoruiop.com/ and clicking Go.
Once jailbroken, you won't have to worry about your certificate expiring, as you will be able to use the new browser based tool to reactivate after reboot.
To make things easier, you may want to add the site to your home screen as a webclip. Once you do so, an Internet connection will no longer be required to re-enable the jailbreak.
This tool does not help you jailbreak or install Cydia; it will only re-enable the jailbreak for you.
Notably, Todesco says that an untether for the iOS 9.3.3 Pangu jailbreak is doable.
"An untether for 9.3.3 is doable, the main issue is that I don’t want to risk f***ing devices over."
