My LED flash is out of place. Possible to move?

My LED flash on my iPhone 16GB is not centered in the hole. When you look straight at the LED from the back, you can see the LED is higher than where it should be. You can see some blackness under it too inside the hole. It's really noticeable when you take close pictures in the dark, as part of the picture (upper part) is darkened. It just doesn't look even.

I was wondering if I could unscrew the back and move the flash around? Help is appreciated. (It's minor, but it's annoying)

Thanks
