Hello, Based on the good reviews here I have an Ultra Crystal screen protector on it's way to me. I also just got a Decal Girl skin for my x. My question is, I have heard the ultra crystal protector covers the black area surrounding the screen (where the Verizon protector does not). It also appears that the Decal Girl design for the front, also goes on that black area around the screen. Do you think I cannot use both of these together, or can I put the Skin over the Ultra Crystal protector?? Thanks!
