1. What is a jailbreak device?
Jailbreaking refers to the process of removing all restrictions imposed on an iOS device. Apple’s devices that can be jailbroken include; iPad, iPod Touch, Apple TV 2 and all iPhone smartphones. Jailbreaking allows root access to system files that can be manipulated to enable installation of apps, themes, and extensions that are not supported by Apple or unavailable for download on Apple App Store.
Is jailbreaking safe?
Although legal in most countries, jailbreaking still involves risks. Here’s why:
- Crashes and stability issues
- Data breaches
Is jailbreaking legal?
Although it is likely to void your warranty, jailbreaking is legal in the United States and is likely to be legal in most countries (though it’s worth checking). That doesn’t mean it will always stay legal. The DMCA (Digital Millennium Copyright Act) in the US had at one point made the practice illegal, but this interpretation was overturned in court.
Why would you want to jailbreak your iPhone?
Many choose to jailbreak their iOS devices to modify the operating system. Some more tech-savvy users find that iOS is too restrictive for their needs and desire a flexible and customizable operating system, implement open-source software and install apps that would have been unavailable from the official store.
What is Cydia?
Cydia is a graphical user interface of APT (Advanced Package Tool) for iOS. It enables a user to find and install software not authorized by Apple on jailbroken iPhones, iPads and iPod Touch devices. It also refers to digital distribution platform for software on iOS accessed through Cydia software. Most of the software packages available through Cydia are free of charge, although some require purchasing

What is checkra1n?
checkra1n is a community project to provide a high-quality semi-tethered jailbreak to all, based on the ‘checkm8’ bootrom exploit.
How do I use it?
Open the checkra1n app, and follow the instructions to put your device into DFU mode. Hax happens auto-magically from that point and the device will boot into jailbroken mode. If you reboot the device without checkra1n, it will revert to stock iOS, and you will not be able to use any 3rd party software installed until you enter DFU and checkra1n the device again.
Checkra1n version 0.9 → 0.12.4 beta
