With the news (that we’ve known) that iPhone 4 is the most popular camera on Flickr, Apple’s Scott Forstall unveiled new camera features of iOS 5. It is much faster and you can access it directly from the lock screen! Another steal from some third-party apps: You can use the volume up button to take photos, turn on optional grid lines to align your shots and pinch to zoom instead of using the zoom slider. You can also hold your finger to lock the auto-focus and aut0-exposure settings for higher-quality snaps.
