One of the things that I like about my android is that it syncs with the contacts in both of my Google and Facebook accounts (and also my other social apps). I heard this can also be done on iphone. But when I tried on one of my friend's iphone tonight, somehow I just couldn't figure out how to do it.
As usual, my best friend, Google, gave me the answer. For the information of someone who may also have the similar issue, hopefully this article can be helpful.
