Jailbreaking is the process of removing software restrictions imposed by the manufacturer on a device, such as an iPhone or iPad, to gain access to its underlying operating system. This allows users to install unauthorized apps, modify system settings, or access features not typically available. While it offers more control and customization, jailbreaking can also expose the device to security risks by bypassing built-in protections, leaving it vulnerable to malware, data breaches, and other threats.
