What does jailbreaking a device typically allow users to do?

Jailbreaking a device primarily allows users to install applications that are not approved by the manufacturers. This process involves removing restrictions imposed by the operating system, which enables users to gain root access to the device. As a result, users can install software from third-party sources, customize system settings, and bypass certain limitations that the manufacturer has set, such as restrictions on app installation from only official app stores.

In contrast, enhancing security features is generally not a consequence of jailbreaking; rather, it often decreases the security of the device by exposing it to potential vulnerabilities. Using only corporate-approved applications is contrary to the purpose of jailbreaking, which is to allow a more diverse range of applications to be used. Lastly, jailbreaking does not restrict users to accessing only public Wi-Fi networks; users can connect to any type of network, just like non-jailbroken devices. Thus, the correct answer highlights the key capability that jailbreaking provides to users.
