H3lix iOS 10.3.3 jailbreak for 32-bit iPhone and iPad devices has been released. It is semi-untethered in nature and here’s how you can use it.

With the release of iOS 11, Apple ended support for 32-bit devices and apps completely. This means that if you have anything older than an iPhone 5s then it’s highly likely that the highest your device will go in terms of software updates is iOS 10.3.3. So, rather than just throw away your old device and upgrade, we have some great news for you in the form of a jailbreak tool called H3lix, created by famed iOS hacker tihmstar.
