I thought this test video was complete crap. They were light on the real life tests and went right to the smash test that grab headlines.
One other thing that was interesting was the washing up part. Watch closely and you will notice he is holding the phone with his palm sealing up the bottom of the iPhone where the connector, speaker and Mic are. Sure he drops it in the cereal bowl, but it does not submerge.
I really hope someone gives us a "real" iPhone 3G test with HQ photo's of the damage (or lack of) after each test.
