How to change iPhone 4 camera settings?

When ever I take a picture, the picture gets saved but is flipped from what I saw on the camera. How do I change that?

When in camera mode, in the upper right of the screen, there's a camera with some arrows going around the camera. Touch that. Instead of the camera lens on the screen side of the iPhone being used, the camera on the back side of the iPhone is used. I use an iPhone 4s. If you can only use the camera that is on the touch-screen side of the iPhone, then just use a photo editor to flip the picture.
