I cracked my screen, and found a good video on YouTube, and ordered the screen from etradesupply dot com and when I got the new screen, the black adhesive strips around the digitizer where not sticky at all after peeling off the clear backing. The original digitizer is held on by strong adhesive and you have to use heat to get it off. From what I can tell there's nothing but the adhesive holding the glass in place. I chatted with someone in China with etrade support and they insisted the adhesive is not supposed to be sticky. I ended up removing the adhesive from the new screen, and cutting thin strips of double sided foam tape and putting the phone back together so I could use it, but the tape I used is a bit too thick, so the glass is not flush with the case... Anyone else been through this? The part must have been from the original Nokia supplier so don't get why it wasn't right.
