Ok Guys, another question..
I tried to reassemble it but now the screen is blank...
Does it mean I broke it too???

Well, I tried reconecting the display, but my guess is that I really broke it..

Oh well... just ordered a couple of screens from china.. now I`ll have to wait for 30 days for it to get here..
I hope untill then someone could help me remove the clickwheel!
