Take pictures with your headphones

One of the major headaches of the iPhone was the lousy quality of photos taken by the camera. The iPhone 4S features a very good camera, but there's a nice little hidden gem for iPhone 4 and 4S users alike.

Now, users can take pictures by tapping on the volume increase button on their headphones. This may seem trivial, but it does make the iPhone 4S a point-and-shoot camera. It also gives you a few feet of room because you no longer have to hold the camera up to your face to take a picture. You can use the length of the headphones wire to take a picture.
