Now, it isn’t without a few caveats, the biggest draw back of which is that it is a tethered jailbreak. Meaning that if you restart your phone you’ll lose the jailbreak (big bummer). Hopefully there will be an untethered version in the future (and if so, this tutorial will still most likely pertain to that as well), but for those who are impatient, here’s how to jailbreak iOS 9.3.3 right now.
I. Before You Begin

Make sure to backup your device to iTunes/iCloud before getting started.
Again, this is semi-tethered for now so rebooting your phone will kill the jailbreak and you’ll need to reuse the app on the phone to rejailbreak.
