Probably the most popular camera-related software for the iPhone on iTunes, Camera+, has been recently updated. With iOS 5, Apple enabled the ability to capture images using your volume button, something Camera+ did in the past but had to give up on the feature.

Now that Apple is officially bringing it back, Camera+ has been updated to support, once again, VolumeSnap. Instead of tapping the on-screen shutter button, you will now be able to snap pictures using your volume button, if you can of course keep the phone steady while snapping them in order to get crisp and sharp images. Follow the source link to update or consult your iTunes or App Store apps.
