What is Jailbreaking?

Jailbreaking allows root access to the iOS core file system and removes restrictions by the Apple. Jailbreaking can run unsigned code, or software, which normally prevented by Apple. Benefit is, it allows users to install patched apps, tweaks, and themes that doesn’t available on the app store. This helps to customize the look and enhance the functionality.
Jailbreaking is most popular with Apple’s mobile operating system, iOS. It also exists on tvOS and watchOS. With this you can add an unofficial application installer to your device. That lets you download 3rd -party applications, tweaks, and extensions. These packages open endless possibilities to do things on your iOS device. Those things can never do with a non-jailbroken iOS phone. Jailbreaking is about feeling your Apple device to let you use the products you paid for in any way you wish.

Jailbreaking Benefits

  • You can install jailbreak apps, tweaks, and themes to customize the look and enhance the functionality.
  • It helps to lock individual apps using Touch ID, or Face ID.
  • Tweaks bring features that are not available to older iPhone. It may hide icon names, adding over four applications to the dock, adding a dark mode, or applying an entire theme, sounds, and all.
  • If you function over aesthetics, jailbreaking can cater to you too. Functionality tweaks can bring improvements to the way your iOS device operates. It helps your phone to perform complex events in response to certain button combinations. It can set your phone to turn off, read receipt in third-party messengers, connect wirelessly to other devices via SSH, and install apps from unknown sources.
These are just some benefits of a Jailbroken device, and there are more.

Can I still use Apple App Store?

Yes, you can use iTunes and Apple app store after jailbreaking your device with no problem. Nothing will change. It only lets you do extra things. It doesn’t prevent you from doing what you did before. The only matter is that some App Store apps include jailbreak detection. It can circumvent for most apps with a tweak.

Is it not legal?

Yes, Jailbreaking is not illegal. The U. S Library of Congress has granted Digital Millennium Copyright Act exemptions for jailbreaking smartphones such as iPhone tablets, smart TVs, and other computing devices. A user who likes to tinker with the ability to change their software can do it without breaching copyright law.

The status in other countries varies. But they do not use it for copyright infringement and never going to a court of law. However, any crime you commit on the device is illegal. If you use it to download paid apps for free, or illegally torrent movies or commit other cyber and copyright crimes, that is an act of breaking the law.

iOS Update and Jailbreak

If you jailbreak your device and update it to the latest version of iOS, you will lose the jailbreak.


It is important to check if the latest iOS software update can Jailbroken before you install it. This means you must wait for a new tool to jailbreak the newer firmware. It will not be a big issue for people who are ready to lose their jailbreak for newer stock features.

People who rely on a lot of jailbreak apps and tweaks have to be cautious about it. Each iOS update patches any jailbreak which worked for previous ones and hackers have to start again to make a tool. When they release recent iOS version and accompanying jailbreak, the preferred way is to back up your device first. Then restore and update your device to the required iOS version. Now jailbreak again using the released tool.

What are the Unique Jailbreaks Types?

There are four types of Jailbreaks.

  • Tethered:

It can only temporarily Jailbreak the iPhone during a single boot. If the user restarts the iPhone for any reason, then the device must be re-jailbroken with a computer (using the boot tethered feature of a tool), each time it turned on. Otherwise, it would get stuck in a partially started state, such as Recovery mode. This can be the worst type of jailbreak because you need a computer if you need to restart your iPhone. This is not convenient at all.

  • Semi-tethered Jailbreak: 
This means the device can start up on its own. But it will no longer have a patched kernel and therefore cannot run modified code. Jailbreak apps and tweaks won’t work on this situation. You need to use a jailbreak tool to start with a patched kernel. Then you can use the jailbreak tweaks again. However, it will be usable for normal functions, unlike tethered jailbreak, which would not boot at all.
  • Untethered Jailbreak:
This is the best type of jailbreak. Little difficult to build them. But it doesn’t have the limitation of a semi-untethered tool. It lets you restart your iPhone, and the kernel will remain patched.
  • Semi-untethered Jailbreak:
It is the same with untethered Jailbreak because it gives you the ability to restart your iPhone. The iPhone is not Jailbroken after the reboot. This means that after every reboot you should re-run the jailbreak app on your device.

It reactivates your Jailbreak to let you use your tweaks. It differs from the semi-tethered jailbreak. You can jailbreak iPhone using an app on your device itself in the semi-untethered jailbreak. So, you need not tether your iPhone to a computer to Jailbreak it.

What are the Best Tools to Jailbreak an iPhone?

There arent any the best Jailbreak tool, there are many. Because tools usually work on a set of firmware before being patched. They are being updated and replaced over time.


You can use one tool to jailbreak iOS 7.1.2 and another to iOS 11.3. The best tool to Jailbreak will be the one that can break the firmware your devices has.


Sometimes there are multiple tools for the same firmware. All released Jailbreak tools so far are free. You dont have to pay for them. There are lots of websites to download these tools from, but always try to download them from the real developer.


Generally, Jailbreaking an iPhone is easy. Navigate to your app drawer and find the installed Jailbreaking tool and open it. Usually you can find the process guidelines there. Make sure to follow everything as the tool mentions.

It is very easy to Jailbreak the iPhone. You can use tools like Cydia Impactor or XCode to install the Jailbreak app on your iPhone.


Sometimes the Jailbreak process faces problems. While the tools try to unlock the device, it can be a mess and makes your device unstable. If this is the case, with your device, you need to use an app that can take your device out of an unstable situation.
