Amusing story about iPhones in "sensitive" environments: I was in a government-related meeting on a sensitive topic. Everybody in the room was asked to remove the batteries from their cell phones. There were several iPhone people who just kind of shrugged and turned the things off. That was okay, but I'm sure if the meeting was more sensitive, they would have forced those people to leave their phones outside or something.

Anyway, I don't know how much credence to place on the dual-camera rumor. I imagine AT&T would take an all-or-nothing approach. Either video-calls work spectacularly, or they don't deploy them at all. Given that their 3G roll-out will take years, and coverage will be spotty, I doubt they'd think they were ready for video-calls.

3G seems to be a guarantee. Any other rumored feature, I'd be less sure.
