This comes from the "contact" section of your profile and is only shared if you type it there yourself.

No, this definitely has things that have been uploaded from my iPhone address book.

Agree - I saw this a few days ago. When they are "syncing" their app they are taking your phone numbers, not just using it to display photos on your phone for your contacts, which is what I thought I remember this started out as.

that's what i thought too, until i read this on that page:

"Facebook Phonebook displays contacts you have imported from your phone, as well as your Facebook friends.

If you would like to remove your mobile contacts from Facebook, you need to disable the feature on your mobile phone and visit this page."

Absolutely not true. They ganked it from my phone.
