Has anyone actually tried this?

How to Get Display Mirroring on Your Jailbroken iPad

It was on the front page the other day and I'm curious to see if it works. I'm interesting in doing it but I want to be sure it actually does what is says it does before I try it since I'm such an ipad noob. I already have the a/v digital adapter.


Edit: I know this is also possible with display out but I'm a poor college student who pinches every penny! I also know I titled the thread "video mirroring" but I meant just mirroring in general.
