8. Set Up a VNC Server
There are plenty of iTunes Application Store apps that allow you to connect to VNC servers on your computers to control your computer from your iOS device, but what about the other way around? If you jailbreak, you have the option of installing a VNC server on your device and remoting in to control it with the mouse and keyboard on your computer.
7. Add Support for More Bluetooth Devices
Apple supports various Bluetooth devices, like keyboards and headsets, but if you want full Bluetooth support, you’re going to need to jailbreak. There are several BTStack packages in Cydia you can download to add more functionality. For example, you’ll be able to pair a mouse with your iOS device, transfer files over Bluetooth, and even add a third-party GPS device.
