owners will see an even greater speed boost. A faster processor means the built-in camera on that phone will spring to life a bit faster. Couple that improvement with iOS 5, and you'll be able to take that shot you wanted to capture quicker than ever before.

Third-party photo app developers have tried to turn the iPhone's Volume Up button into a shutter release before, only to get shot down by Apple. In iOS 5, Apple has taken the hint and made the hardware tweak itself. Now just tap the button to snap a picture.

The Volume Up button isn't in the ideal spot for a shutter button--the lens of the camera is in the lower right corner while you're shooting--but as long as you are careful not to put a thumb in front of the lens it's a great new option to have. Using the button should feel more natural to use than tapping the screen; it will also minimize camera shake.
