So the owner of our company has an iPhone, and was recently impressed by a person who apparently arrived and used his iPhone to send an image, wirelessly, to an external screen (small screen, but larger than iPhone, described as between 7 and 10 inches), for the purposes of sharing a PowerPoint presentation without having to bring a laptop or have everybody stare at his tiny iPhone screen. Anyway, I'm not having much luck at all figuring out what the guy could have been using since I wasn't there. I have very little experience with Apple products, and have found a few YouTube videos demonstrating the iPhone 4 being used with the iPad VGA cable adapter to connect it to a screen, but that isn't what he saw, and he was very specific about it being wireless. I know there are wireless display systems out there, but I'm not sure which ones would work with an iPhone. I don't even have an iPod, so I can't go testing out the different hardware myself.
