Answer to: black plastic bezel around screen replaceable?The bezel and digitizer are one piece, and it's really hard to separate the digitizer and LCD without breaking one or the other.
Answer to: How to Replace Touch Digitizer?I find it very difficult to get the LCD and digitizer apart without breaking one or the other. Use a heat gun on the adhesive and go very, very slowly. Also keep in mind there are two Evo LCD's out there, made by two different manufacturers, and with differently sized connections, so make sure you get the right one. One has a skinnier cable, less than 10mm wide, and the other is closer to 20 or so.
