New Facebook app Hello gives you personal caller info

Caller ID is a pretty limited thing, with unknown numbers just showing on screen as a bunch of numbers. You really have no idea who's calling, but Facebook wants to change that.

With their Hello app, you log into your Facebook account and then use it as a dialler. When someone calls you, you'll see some of the information they share publically on Facebook, so you'll get a brief look at what they do and possibly even their age, as well as whatever their latest profile picture is. Here's how it works.
