I use this program called iShowU HD. It isn't free, but it is reasonably priced. You can record an app running in the simulator or anywhere on screen. ** update Nevermind, I was thinking about capturing video on the mac. I haven't seen anything that runs on the device.
So its possible to use the PC program IShowU HD to record an app. What do you mean by a " simulator" can you explain that please? I heard of something called simulator but never found out what it was
