MobileNotifier is a great start to what iOS notifications should really look like. Keep in mind this app is still in beta before you go replacing LockInfo. I've been playing with MobileNotifier today and it's got a lot of potential.
One thing I really like is the ingenious way MobileNotifier makes use of the wasted space while multitasking. When the tray is pulled up, the top of the screen is really just a bunch of empty space. Why not make use of it? MobileNotifier does by putting all your notifications in it. The latest beta also adds support for a lockscreen mode. The app doesn't currently have any built-in settings but we'll have to keep in mind it's an early release of the app.
With an early release comes compatibility issues and bugs. BiteSMS currently doesn't seem to want to populate in MobileNotifier for me. Hopefully this and several other compatibility issues will be addressed in a future beta. Hit the jump for a couple more screens and to find out how you can grab MobileNotifier!
