I just switched to an Android phone so apologies if this is old news, but as i make a call to people it pops up their last Facebook status on the dialer screen.
I can appreciate this may sound like a total waste of time but i've been grateful of it so many times now!
The effect is almost like my phone could read my mind and it's saying something like "ohh, you're going to talk to so-and-so? Well here's something current to talk about!"
