Just curious, have you done this type of repair before? The first phone I helped replace a screen for went badly, due to my friend breaking a ribbon. If this is your first repair, I would ask a friend or someone who has done this before to help. My friend's droid was totalled b/c of his mistake. I would hate to see your N9 suffer from a similar fate, considering how much more expensive it is, best of luck. There are services online that do screen replacements for a good price.
