This is a cool way for you to protect your phone and also to remind you, your device can do it too. With AndroidLock you have 9 points on your lockscreen where you will have to connect the dots in a pattern of your choosing to unlock your iDevice. Numerous patterns are possible with this tweak, you can set your pattern as many different times as you wish. Personally, I like this because it keeps my phone safe, as well as making it easier to have a pass code instead of numbers. AndroidLock is free in Cydia.
