what is jailbreaking an iphone

Jailbreaking an iPhone is the process of removing software restrictions imposed by the manufacturer to gain unauthorized root access to the operating system by exploiting its flaws. This allows users to download and install unapproved apps, personalize the iPhone more, and access the devices file system. Jailbreaking also opens the possibility of using software to unofficially unlock carrier-locked iPhones so they can be used with other carriers. However, jailbreaking an iPhone modifies the operating system, giving unauthorized access to the jailbroken devices core software and code base, which can expose the device to hackers and viruses. Cybercriminals may jailbreak an iPhone to install malware or target jailbroken iPhones on which malware can be installed more easily. Apple is against jailbreaking or unauthorized modifications of iOS devices as it can cause security vulnerabilities, shortened battery life, and instability in its software.
