Have you heard of Veency? Veency is a Cydia app that allows you to connect to your iOS device from a computer via a VNC viewer. In other words, view and control your iOS device from your computer. When you connect, it should look something like this.
It's pretty cool. You can find Veency in the Cydia Store. If you need help using it, I have created a tutorial here. This is one of the must have apps from Cydia. :) Go check it out!
