OK ... my bad. I see the problem. I originally entered iPod ... when I should have written iPhone. I went back and corrected it. I am deathly sorry (Geeezzzzz).
Anyway, I don't know a lot (so lighten up). I doubt they were on Wi-Fi. In fact, I know they were not, because at one point one of them asked me if I was getting '3G' (mentioning that they were). We both looked and my 3G light was on, but no bars on it or the Verizon signal strength indicator next to it.
