Haiti earthquake: Trapped under rubble? There's an iPhone app for that

Despite the rather irreverent title to this submission, it is a pretty amazing story. It highlights the crazy implications of having n entire world's worth of knowledge at our fingertips at all times.

There are a few things I'm really unclear about though, namely why isn't it mentioned that he contacted anyone over the phone or internet to let them know where he was, or that he was alive, or to get medical advice for that matter. Also it mentions he was trapped for 65 hours. No possible way that an iphone battery could last that long, is there?
