Preach!
Whats the point of being shot on iphone if they likely used other hardware on top of it.
They are not trying to teach people how to shoot like the ad. They are only advertising that it can be done. I think that it is up to the consumer to know/figure out what works for them based on availability and finances. There are tons of rigs that you can get for an iphone that will stabilize a shot and allow you to get the clarity you want. Not all of them expensive either.
