I'm in the same boat as you haha
Well, didn't really look for updates, but I bet the moment this gets published it's on jailbreaking sites everywhere around and Youtube will be stuffed with it in your recommendations if you usually watch jb videos so Youtube's algorithm knows you're into that sorta thing.
When my fiancée got her iPhone 4s I bothered, now I still would like to have it of course, but the new iPhone being around the corner and me renewing my contract by then I don't feel a lot of pressure to jump through hoops for getting it a little earlier anymore!
After all I don't have an Apple TV but would use Air Server instead. A great tool if you ask me, although a little buggy at times.
I recommend anyone interested in combining the beauty of Air Play (audio and video) with their big desktop screens to go for it.
Oh and in Cydia there is even Air Server for iOS, so you can mirror to iOS, too.
Theoretically, this should enable you to mirror iPhones to iPads, quite nice if you say want to lug just one device around the house and check your SMS/whatevers via iPad.
That's just one usage scenario, but certainly I adore this little application.
