Beware of your profile pics, or your boss might get one of you doing something you don’t want them to see! What happens is, [Facebook 3.1] takes [all] the emails and phone numbers on your iPhone and sends them to Facebook. It then cross-checks and syncs them back to your iPhone. That’s a major security flaw right there! It should only sync the ones you’re friends with.
So for an example I have my coworker’s email and cell but I am not her Facebook friend. All of a sudden when I got a call from my coworker I saw a picture of her in a bikini because that was her [Facebook] profile pic!

Given the more casual (read: sometimes drunken and debauched) profile pictures that appear on Facebook, and the potential from cross-contamination between trusted friends and respected colleagues, if this is widespread the potential for embarrassment is high. Even if this is an isolated or semi-isolated incident, as more and more social network contact pools are integrated together, its worth remembering that anything — and everything — you put on the internet will eventually be seen by those people you least want to see it.
