The iOS 7 lock screen was made to be just that, a lock screen, so it's pretty limited in terms of functionality. We're able to add wallpapers and easily access the Control Center or Notification Center (unless we disable that access through our settings), but other than that, it's pretty bland.
I've recently covered a jailbreak-only mod that lets you change the "slide-to-unlock" text on the lock screen to say anything you want, but we can do so much more than just that. So, in this softModder guide, I'll be showing you how to revamp your entire lock screen with a new theme (don't worry, you can keep your custom message).
In order to get this theme, we'll need to add the source where it's available. Open Cydia, then select the Manage tab -> Sources -> Edit -> Add -> and enter "http://patrickmuff.ch/repo/".
After the source is added, select it (Patrick Muff), then install iOS7 RisingBars Cydget. This theme will replace our stock date and time display with an active flow chart that displays time in a military (24 hour) format.
We're just about done. Next, open your Settings application and locate the Cydget options. Open and select Lock Cydget Order and check RisingBars, then restart your device.
With Cydget, we can also set an order of themes to apply and cycle through on the lock screen by pressing our home button—something to keep in mind if we get another theme we want to apply.
In my opinion, try to pick a elegant, preferably black, wallpaper to get the best looking lock screen.
