Dan Pražák It's only been less than two months since Apple made iOS 13 available to regular users, and the first system jailbreak has already been released. Specifically, it is the public beta version of the checkra1n tool that it uses security errors checkm8, which was discovered last month and Apple is unable to fix it with a software update. This will also make the jailbreak permanent to some extent.
Jailbreak checkra1n must be done through a computer, and the tool is currently only available for macOS. Due to the flaw that checkra1n uses to break system security, it is possible to jailbreak virtually all iPhones and iPads up to iPhone X. However, the current version of the tool (v0.9) does not support iPad Air 2, iPad 5th generation, iPad Pro 1st generation. Compatibility with iPhone 5s, iPad mini 2, iPad mini 3 and iPad Air is then in the experimental phase and therefore jailbreaking these devices is risky for now.
Despite the above limitations, it is possible to jailbreak a wide range of iPhones and iPads. It is enough to have any version of the system installed on them from iOS 12.3 to the latest iOS 13.2.2. It should be noted, however, that for now this is a so-called semi-tethered jailbreak, which must be re-uploaded every time the device is turned off. Additionally, checkra1n is only recommended for more experienced users, as the current beta version may be plagued by bugs. But if you are one of them and want to jailbreak your device, you can follow the steps below of this manual.
Checkra1n is the first ever jailbreak to exploit checkm8 bugs. This is related to the bootrom, i.e. the basic and immutable (read-only) code that works on all iOS devices. The bug affects all iPhones and iPads with Apple A4 (iPhone 4) to Apple A 11 Bionic (iPhone X) processors. Since it uses specific hardware and bootrom to function, it is not possible to fix the error with the help of a software patch. The processors (devices) mentioned above basically support a permanent jailbreak, i.e. one that can be performed on any version of the system.

The undisputed fact is that Apple's security and privacy are just bullshit for adolescent ignoramuses.
There are similar mistakes everywhere. That's not to say that someone doesn't take privacy and data protection seriously. What matters is how he deals with it. And if it does not concern the last two processor lines, it is obvious that the error has been fixed and that it was more at the architecture level.
