I also bought a screen from the same place. Delivery was fast and the screen looked good.
I followed the video tutorial (http://youtu.be/9dxsTGpGRhs) but after reassembly my phone wouldn't start anymore... I don't know what went wrong, but according to the repair shop I brought it to it cannot be repaired anymore. So be warned, screen replacement can ruin your phone...

Guess I'm in the market for a new phone now. Anyone have recommendations where to buy a new N9?
