You have to take it off from the top of the phone. It comes off pretty easy. I usually will put my fingernails in one of the corners in the top of the phone and give a little pull and it pops right off.
The one nail I had that showed promise is now destroyed beyond recognition. Is there some tool I could use in lieu of a revised six month personal grooming regimen?
Never mind, I got it. For those having trouble, my problem was I was trying to pull the screen OUT of the back... pressure on the edge of the screen. You need to pull the case OFF of the screen... pull on the case.
