sync facebook contacts

Hi I have a ipod touch 5G and would like to know if there is any way to sync my facebook friends. All contacts or list of my best friends.

or there will be some form of organized matener all my contacts in and I'm a fan of the organization.

Because if not all are synchronized but only two or three. But the thing is that I have not saved my contacts on my ipod and appear as facebook. I await your response and thank you.
