Remove the two screws holding the camera lens cover on. Keep in mind they are two different sizes. Short one up top, longer one on bottom. Use a small phillips head screwdriver. (sorry for removing them before taking the pic)
Remove the camera lens cover. I used my sharp pointed tweezers to pop the bottom of the cover up. It is also held in with small clips, much like the battery cover.
Save the volume/power button from the old cover and reuse it with the new camera lens cover.
