Updated with new question:
I'm taking my Nokia 3390 apart piece by piece. So far, i have removed the back cover, the battery, the SIM card and the faceplate. What i'm staring at is on this picture. Now, i need to remove the LCD. According to this guide, i "must insert a tiny, flat head screw driver and pull the white away from the LCD area and push the LCD up". I think have a screwdriver like that, but what about the screws themselves? They apparently hold the LCD board and the mainboard together, yet the guide says nothing about removing them, and shows the two board separated on the next picture.
