I hope you guys enjoy this. It's a little hack I've been wanting to do for a bit, but I had to wait for the iPad 3 jailbreak, as that's the only iOS device I have. Let me know what works, doesn't work, etc, and have fun with it!
Oh, cool. I looked around before I built this and couldn't find anything. I wanted to avoid writing my tweak against Safari since it changes so frequently, but it looks like his approach is pretty straightforward.
