I was fairly impressed with the look of the passcode screen after configuring SleekCode. Have a look at our video walkthrough for more information.
Once you install SleekCode, you’ll find a new preference panel in the stock Settings app. Inside the preferences, you’ll see 5 different switches assigned to specific settings along with a Respring button. Each switch can work independently of one another, and corresponds to the blur, alpha, and button ring mentioned at the outset.
Each change that you make to SleekCode’s switches requires a respring before the changes take place. Thankfully, that is easily accomplished due to the Respring button at the bottom of the tweak’s settings.
SleekCode is available for free at Cydia store, you can grab it from BigBoss repo. It also works great on iOS 8 ;)..
