Just got done doing two weeks of shooting in Glacier National Park, used the iphone for video for a blog, did great. It also did great in my underwater housing when I simply taped it / rigged it to the collapsed port. I used it underwater so I could check light as this is film based shoot, left the digi-crap at home. The hardest thing was to trigger the shutter. It is pretty stupid you can not assign another button on the phone as the shutter / video on button, not all of us are tech head cubicle people..
