For all of you non-jailbreaking iPhone pho­tog­ra­phers, your iPhone is going to be a fully-functioning instant, always-on-the-go pocket cam­era with the iOS 5:

Since your iPhone is always with you, it’s often the best way to cap­ture those unex­pected moments. That’s why you’ll love the new cam­era fea­tures in iOS 5. You can open the Camera app right from the Lock screen. Use grid lines, pinch-to-zoom ges­tures, and single-tap focus and expo­sure locks to com­pose a pic­ture on the fly. Then press the volume-up but­ton to snap your photo in the nick of time. If you have Photo Stream enabled in iCloud, your pho­tos auto­mat­i­cally down­load to all your other devices.

Now, the ques­tions are: 1) Can we launch a third-party cam­era app from the Lock screen? 2) Do we still need this?
