I have to ask: have you ever used a lockscreen notification app? Once you do, you'll realize the value of having all the information that you might want to see at a glance immediately on your lockscreen.

LockInfo, for instance, lets you choose the type of information to display as well as how to display it. You don't see anything you don't want to see.

Then once you use something like it, you can't go back. There are a ton of people who jailbreak just to install LockInfo. That's how good it is.
