I stumbled upon one great app from BigBoss and it is called SleepFX written by Malcolm Hall! You can generally get it from Cydia from BigBoss source. Although so, some of you might be getting it from other sources and for free instead of paying. Well that is totally up to you where you get it.
Some of you might have gotten SleepFX but it generally crashes after 5 or 6 times locking and unlocking. The only way to get it working again is to respring it and this is totally uncool. You might want another way around so basically these steps below will help you solve that problem!
