Strange site on the convention floor

I noticed something strange last night--people walking around the floor cannot gain access without proper credentials. These are usually worn around the neck on a laniard. I saw a rather casually dressed young man (jeans and knit shirt), with what appeared to be credentials around his neck. But it was an iphone on a laniard with the image of the GOP elephant! Kind of looked like the credentials worn by most of the delegates. This is pretty surprising that he got on the floor (I suspect without credentials or maybe he did, but put them away)?--no one noticed this guy that I could see. He was out of sight after he passed by. I wonder?
