<p>UPDATED FOR IOS 4.3.1
This is an "Invisible Slider" Updated so that will work on the new "iPhone 4" as well as other devices like 3g, 3gs, and iPod Touch. Lets you see more of your lockscreen and might keep some nosy people from unlocking your phone too. You simply swipe your finger across the bottom like normal. The other sliders for "call answer" and "power off", work as normal and are not invisible. Install and activate with Winterboard</p>
