Oh brother! This thread turned into a horror story.
I have removed the screen myself with no trouble at all. Just used my fingernail to completely lift the screen. I had to repaint the black edge of the screen on the back (The paint had peeled tiny bit on the edge, so it looked like it was cracked in a certain position). A permanent marker did the job perfectly.

Ah, the N9 could have been the best candidate ever for a weather-tight phone. Just add a sealing here and there and a few things designed a bit differently.
Anybody noticed how much dust these phones collect inside?
