Is that force sufficient to truly affect the capture of an image with as low a focal length as the iPhone has? I was going to say that using the volume buttons permits the user to hold the phone in a proper camera stance (hand underneath the base to improve stability, no elbows out), but having just held an iPhone 4.0, I saw where the camera is placed and where the volume button is relative it, and how to properly hold the phone. It does not seem like the volume button is in the right spot for where the camera is to even use it like a proper camera. You're going to have to hold the phone weird to take a picture without your finger in the way to use the volume button as a shutter. tl;dr. The volume button isn't even in the right spot to use it as a shutter, and I wager pressing the volume button doesn't have any true advantage. For a phone that has a shutter button in what I perceive as the correct location, see the original Motorola Droid.
