The correct answer is 'False'. Jailbreaking a mobile device is not a recommended security practice. While it allows users to gain full access to the device's operating system and install unauthorized apps, it also compromises the security by bypassing the security controls put in place by the device manufacturer. This can make the device more vulnerable to malware, security breaches, and other threats. Manufacturers' updates and patches that address security vulnerabilities may no longer be applicable, leading to an even less secure environment.
