Arguably the biggest change to iOS 5.1 when compared with its predecessors is the Lock screen camera functionality.

Instead of double pressing the Home button to reveal the camera icon on your Lock screen, the camera icon is a permanent fixture.

Revealing the actual camera also works quite differently than in times past. Check out our video walkthrough of the new iOS 5.1 Lock screen camera functions inside…

With iOS 5.1, instead of tapping the camera icon, you slide up on the icon to reveal the camera.

The Lock screen camera still respects passcode locks, so that you can only take shots and review shots that were taken while at the Lock screen.
