Actually doesn't matter one lar. If you take out 1, then try to apply and it doesn't look right, just take out 2 and apply the other way AFTER wiping the screen. You will know it looks wrong when you are applying the wrong layer.
Just got my SGP Crystal from Webbyboy today. Two thumbs up to him for his service and price! By looking at the drawings on the cover, I installed it by removing layer 1 (top layer) first. You should remove layer 2 incrementally as it is below the actual layer that is applied to the phone. It's quite simple actually, just stay calm and do it when you're in a positive mood!
How to know if the orientation is correct? The small hole in screen protector should be on the top right for the front facing camera.
