I've done a lot of searching and still can't seem to come up with a definitive answer. I'm a teacher and would love to mirror my Ipad1 or Iphone4 (both on IOS5) to the projector at work. Currently my desktop computer is hardwired to the projector, so the computer monitor is mirrored by the projector. This works fine, but only when I'm sitting at my desktop computer (which makes it so that I have my back to many students). I'd love to be able to stroll through the classroom while doing math with my fingers on the Ipad. There are also times in which I'm facing my students and have my back to the screen. So I'd love to be able to also use the Ipad while the students see it mirrored on the screen. I would prefer it wireless, but I don't mind a cord from the projector (if there is such a cord that will link it to the ipad1. Thanks for any advice.
