Did you know Facebook stores all numbers you have on your phone?

Um, if your friends put their mobile numbers on their Facebook page, then the number shows up right beside their name when you look at your friends list. It's not accessing the numbers on your phone, it's accessing the numbers they posted on their own pages, of their own free will. I dont put my number on my page, but many of my friends do. Some of these friends are contacts in my phone, some aren't. But everyone who posts their number will have it show up beside their name on a Facebook friends list. Facebook didnt access your phone. This is why you can't find any information about it.
