Watch the video below demonstrating Intelliborn's IntelliScreenX. It's an amazing looking app that adds new functionality to the iOS 5 Notification Center and makes it available on the lock screen. Other features include a pretty slick quick setting widget (top of the screenshot above), collapsable sections, an auto-updating Twitter ticker and full pages for Twitter, Facebook, Calendar and Mail.
The bad news? It's a jailbreak app. It's expected to be released next week and I think that I'm going to jailbreak my iPhone 4 just for this app, it looks like a lot of fun.
