If you are not satisfied with your ‘slide to unlock’ option, to unlock iPhone/iTouch then AndroidLock is for you. AndroidLocks lets you draw the pattern and stores it, and you’ve to draw that pattern to unlock. This is really cool Lock screen app which provides privacy, also provides an alternate way to lock phone. You can set the lockscreen pattern by going to Settings>AndroidLock, which is quite simple and easy to do.
The only thing that I didn’t like about this is that you can’t reduce the shade of lockscreen dots, otherwise this is cool LockScreen app.
AndroidLock is available on cydia under BigBoss repo for free.
