One way to improve security on the iPhone is to slow down passcode entry. With the jailbreak tweak Combination Lock installed, would-be intruders may give up while dialing on the rotary padlock screen. In reality, this mod for the lock screen keypad is purely cosmetic. Rotating the interface to hit all of the numbers in your passcode will unlock the device, just like a padlock. While this can be fun, there is an easy way to access the device more quickly.
When needed, digits can be pressed directly just like on the normal keypad. This means that rotating the combination lock is not required to unlock iOS. Once installed, there are no options or settings to configure. Combination Lock will show lock screen wallpaper colors through the rotary portion of the lock screen.
Combination Lock is available from the BigBoss repo on Cydia for free. To start customizing iOS, click here for instructions on jailbreaking iOS 8.0-8.1.2. Those with older firmware can jailbreak with Pangu (iOS 7.1) or evasi0n 7 (iOS 7.0). Find out how to purchase and install Cydia tweaks with this guide.
