Finally he used the "light" from the phone screen to attract their attention.
So much for aGPS. I have seen other problems too. A good chip GPS doesn't usually have those problems.

Yeah, I read about that. It didn't have anything to do with aGPS (which will work as well with a sirf III chip as any other gps chip); it had to do with the fact that the map on his phone wasn't appropriate for backwoods use. I.e., the gps showed where he was fine - it's just that being a blinking blue dot in a featureless green map won't help anyone find you.
The fact that the hiker didn't bring an actual map and that the only flashlight he had was the flashlight app on his phone are probably pretty good examples of his preparedness.
