iPhone saves a life

It's true. A man trapped in the earthquake in Haiti this week is crediting his iPhone with saving his life!!!
He used the iPhone screen and his digital camera to shed light in the dark spot he was trapped in. He made his way to a safer spot to wait for rescue. He then used a "medical app" he had installed on his iPhone to diagnose and treat his wounds.
I hope I am never in this situation but what a great comfort to know there are tools that can help in such times.
