Its more than 20 Hours that I have been working on iOS 5 and looks like there are a lot of undeclared features to be discovered in iOS 5. One signicant feature that I found was that you can open your camera.app from your lockscreen. All you need to do is to just double tap your Home button. The “Slide to unlock” box will shorten its width and will show a camera icon on the right side. The screenshot below shows this feature.
After you click the camera icon, it will open the camera app, and you can take pictures with your Volume buttons. Pressing the Volume Up button will click a pic for you.
