The best part of the current Jailbreak solution is that it supports the currently available stable version of iOS. After so many years, the Jailbreak tool developers have finally achieved a milestone on the latest stable version of iOS. There is a lot of time until the release of stable iOS 13, so if you are currently enjoying iOS 12.4, you can unleash the real potential of your device by Jailbreaking it.

About Jailbreak

In case you don’t know, Jailbreak gives applications and scripts access to the root of your iPhone. In the intact form, Apple doesn’t allow any kind of modifications on its iOS. There are certain certificates which prevent any third-party or modified scripts from accessing any internal file of your iPhone’s system. When you Jailbreak your iPhone, you certainly say goodbye to all the security certificates and opt for a less secure device which has no checks in the play. This, in a way, is not a good idea, but at the same time, it gives you a lot of freedom to customize the handset or iPad. Users can change the UI of their Jailbroken iPhone, they can add new features, change the behavior of the buttons and so on.
