First, yes I have read the thread about disassembly of my pearl.
But since no one has warned me off I'm going to try and replace the LCD screen on my 8120 with the LCD screen from my old 8100.
PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE
Stop me now if this is a really bad idea. I could just go back to using my 8100. I really don't want to end up with both phones ruined!
