For those who have problems melting the glue, a sharp knife or a flat screwdriver around the edge will do. Just force the old screen off. Be carefull with the metallic ring around the screen so it dont take to much damage. There is nothing under the screens edges that can take damage, only a wire from the center of the glas down to the home button. And from earlier posts, be carefull with the back and option butto, as there is censors glued to the screen.
