Today, with iOS 5.1, Apple’s added a second gesture to the lock screen.

Previously, getting to the camera required a tap on the camera button, which only appeared after double-clicking the home button.

While that’s not that convoluted, in hindsight it clearly lacked the ease of discovery Apple usually ships features with.

The new gesture, with its ever-present icon is much easier to discover.

Apple’s even taken care of those of us trained for the old way of doing it — tapping the new button makes the screen jump, showing off the movement needed to now launch the camera.
