How does the new facebook application for blackberry work?

[Snowy]

How does it match the contacts in your phone with your friends on facebook? Some of my friends pics showed up in my contacts but others did not. So does it match phone numbers, names, or email? What about if the person has downloaded facebook on the blackberry but does not have their phone number listed on facebook? Will it pick them up then if you do not have their entire name listed on contacts list? Thanks to anyone who can help me answer these questions!

I would seriously suggest you not installing that app on your phone. It totally screwed up my BB calender. The only good thing it did was put the pictures of the people from facebook in my contacts but everything else was a mess.
