I thought that, perhaps, if you have Facebook on the iPhone, it might have some settings to integrate with your Contacts on the iPhone as well, but I've been through the settings on my iPod Touch (pretty
much an iPhone without the cellular radio) and I don't see anything in either the general settings, the Contacts settings, or the Facebook settings that might lead to it. Thus, I'm stumped and don't know what to suggest. One last thought, though. Do you have
any add-ins enabled? Click the Options gear and choose "Manage add-ins". The only other thing I can think of is that one of them may be affecting what you see.
Sorry I couldn't help more.
** Edit **
I just found a setting in Facebook on the iPhone that says "Upload contacts". Tap the three bars at the lower right of the Facebook app, slide down to Settings and tap, tap "Account Settings", then tap
General, then tap "Upload contacts". I have no idea whether or not this ties in at all because I have it disabled, but it's worth checking.
