It's possible that you previously synced that number. Can you email me directly with your Facebook profile ID or alias? I'd like to investigate: [email protected]

EDIT (1 hour later): I haven't received your email and we haven't been able to reproduce your bug. Can you email me (even if it's just user error) with a more detailed description? I want to make sure we follow up on this.

I can provide you with my facebook name, but I don't think you'll be able to reproduce -or- see anything with that alone. (It's not really a 'bug')

I am simply seeing phone numbers of facebook friends (on my "facebook phonebook" page) who 1) do not have any phone numbers listed in their FB profiles, and 2) that I do not have phone numbers for in my own contact list on my iPhone.

What you're describing is a bug that hasn't previously been reported to us. Why are you hesitant to follow up via email so that we can investigate?

I am not hesitant to follow-up via email. I sent one to the address you supplied above and it hard-bounced. Beside, what will my facebook user name provide you? You won't be able to see my account or phonebook page. Who is the "us" you are referring to? The domain you provided is company.com? Are you a facebook employee?

EDIT: I see from your HN profile you are affiliated with FB. Perhaps I am misunderstanding where to send you my info? [email protected] is returning an invalid address error.

EDIT 2: Sorry, Sam. I think I got my mail to you the second time around. Apologies.
