One of the many reasons that users jailbreak their iOS device is to customize the various UI elements. BlurSlide is yet another customization tweak that brings a new look to the 'Slide to Unlock' slider.
Developed by CP Digital Darkroom, BlurSlide allows users to change the original Slide to Unlock design to that of iOS 7.1.x's power off slider style, which features a round movable knob with a blur background. Yet, the best thing about this tweak is that it provides a lot of options to customize the slider the way you want. Although the tweak is still in the beta phase, it worked smoothly without any issues on my iPhone 5s running 7.0.4.
