Dennis Quaid and David Koechner (the sports guy in Anchorman) on the tonight show snapping pics and showing baby pictures with their iPhones.

Note that none of these cebs use a case on their phone. this could mean several things, like; a case would make it ugly and they can afford to drop or a case would hide that its a iPhone and they want people/us to be aware that they do have a iPhone (commercial?)
