Every iOS device has a lock screen, regardless of whether or not the passcode is set up for security. Sliding to unlock not only reveals the home screen, but Apple has designed the transition to be a smooth and fluid motion. Only thing is that everyone’s device has the exact same zoom and fade animation.
Now with a jailbroken device and the free tweak LiveWire, the unlock animation can be changed to something more interesting. The developer HASHBANG Productions describes the new animation as a sliding doors effect.
After LiveWire is installed from Cydia, unlocking iOS results in the lock screen splitting down the middle and spreading open just like elevator doors. The animation is smooth and fades perfectly, just like the default one that’s built into iOS. There are no settings to configure and no icon will be added to the home screen, only the unlock animation will be refreshed.
LiveWire is available on Cydia from the BigBoss repository for free. Check here for instructions on how to jailbreak iOS 6.x with evasi0n. You can also find out how to purchase and install Cydia tweaks with this guide.
