What is Jailbreaking in iOS?

Operating systems like iOS provide mobile users with a secure and powerful Sofware environment for the day-to-day usage of their smartphones. However, iOS comes with several restrictions to the file system by default. Users can’t install any application without AppStore or uninstall the preinstall applications with these restrictions. The user has to break these restrictions to install an application without AppStore or uninstall preinstalled applications. On iOS devices, breaking these locks is called jailbreak.

Jailbreak refers to privilege violation on the apple devices, which is mainly performed to remove software restrictions provided by Apple on iOS, iPadOS, tvOS, watchOS operating systems. Typically, a jailbroken iOS device is given root access to the operating system to install the applications that are not available on AppStore. Apple doesn’t recommend jailbreaking an Apple device. Moreover, it views jailbreaking as a violation of the end-user license agreement.

Reasons for Jailbreaking

One of the main reasons for jailbreaking is to expand the list of default features provided by Apple. There is a strong checklist for the Apple developers to submit their Appstore Connect and Apple checks for compliance with the iOS developer program license agreement.

It rejects the application which doesn’t follow the criterion of Apple’s app distribution policy. Apple doesn’t permit applications that crash on the device and doesn’t appear good on the screen. Also, if the application uses certain device resources without defining their permissions, devices may also be jailbroken to install malware.

Jailbreaking enhances the possibility of installing software that can unofficially unlock carrier-locked iPhones. The unlocked carrier-locked iPhones can be used with other carriers as well.

Jailbreaking also allows the installation of pirated software on iOS. However, such applications are not available through the App Store. Consumer software is restricted to be installed using App Store, such software can be installed via jailbreaking.
