If you use an Android device for a while, you are familiar with the lockscreen always coming on when you don’t want to.
This is why WidgetLocker Lockscreen was probably invented. It allows the user to be control the look, feel, and layout of the lock screen.
The App allows the user to add widgets, app shortcuts, and slick slider shortcuts. You can completely change what you want without unlocking the Android device itself.
These “sliders” can be put in from selectable styles or from user-based themes. Customization comes from Slide-to-launch camera or slide-to-call someone else.
My Source says that “if you use Android, this must be on your phone”. If you want to try it out, it will cost you about $2.99 on the Android Market here.
