The word "jailbreaking" is mentioned a lot in relation to the iPhone. Some people may have told you that you need to do it to your iPhone. Before you do anything, make sure you understand what jailbreaking your iPhone means, along with its risks and benefits.

Jailbreaking Explained

Jailbreaking changes the operating system running on an iPhone or iPod touch to give you more control. With it, you can remove Apple's restrictions and install apps and other content from sources other than the official App Store (the most popular of these is Cydia).

Jailbreaking has often discussed along with unlocking. While they are similar, they're not the same. Unlocking is a legal a right that all consumers have to move their phones from one phone company to another. Jailbreaking, on the other hand, is a gray area.

What You Can Do With Jailbroken Devices

Some of the things you can do with jailbroken devices include:

  • Customize look and feel of your iOS device
  • Delete the built-in apps that come with the iOS in a complete way than the similar feature in iOS 10
  • Install apps that are not available in the App Store
  • Get paid apps for free (sounds good, except that's theft and therefore illegal)
  • Download music, videos, ebooks, and other content for free (in some cases, this is also theft)
  • Access the iOS filesystem, something that's normally hidden from users.

Arguments Against Jailbreaking an iPhone

The arguments against jailbreaking an iPhone include:

  1. Unreliable Operation. Apple tightly controls how its devices work, limiting your ability to customize your devices. Apple prevents these changes to ensure that the devices operate smoothly, with fewer errors, more security, and offer a high-quality experience. Jailbreaking gives you control, but can also introduce problems and instability.
  1. Security Concerns. Because Apple requires that users only install apps from the App Store, all apps offer a minimum of quality and security. This reduces security flaws and prevents spam and malicious apps from infecting your device. Jailbroken devices can be attacked through apps that are not approved by Apple.
  1. Vulnerability to Attack. Generally speaking, the iPhone is the most secure smartphone platform and sees the fewest hacks, viruses, and other attacks. The only time that an iPhone is very vulnerable to attack is when it's been jailbroken.
  2. Upgrade problems. Jailbroken devices can be hard to upgrade to the latest version of the iOS. This is because new versions of the iOS often close the code loopholes used by jailbreaks. You may not be able to upgrade your OS and keep the jailbreak. 
  3. No more official support. Jailbreaking voids an iPhone's warranty, so if you have problems with your phone, you can't get support from Apple.
  4. Technical Complexity. Jailbreaking isn't always simple. Doing it right can require more technical skill than the average person has. If you try to jailbreak without knowing what you're doing, you can seriously—even permanently—damage your iPhone.

Arguments For Jailbreaking an iPhone

On the other hand, the arguments in favor of jailbreaking the iPhone include:

  1. Freedom of choice. Advocates of jailbreaking say that Apple is denying you the freedom to use devices that you own. They argue that Apple's controls are too restrictive and that they prevent people who want to modify their devices to learn from doing so legitimately.
  1. Removing restrictions. Jailbreakers also say, sometimes correctly, that Apple's business interests can cause it to block apps from the App Store that would otherwise work well. They say that you should have access to those apps.
  2. Getting content for free. A less noble, but still true, argument in favor of jailbreaking is that it makes it easier to get paid apps and media (music, movies, etc.) for free. This is piracy and stealing from the people who produce that content, so it's not a good argument in favor of jailbreaking. Still, it is certainly one benefit for the unscrupulous.
