For this tweak you are going to need a Jailbroken device. What this does, is it allows you to snap photos with your native Camera App by pressing the Volume Up button instead of the on screen tap. This makes it much easier to take photos in every way, especially on older devices where you can't see the tap. FastSnap is available in Rock for $.99 with a 9 day free trial.
