How can I record a video of an iPhone app? I can't use the Simulator because the application is very OpenGL-heavy and uses an accelerometer/gyroscope.
You can have the iphone output video and capture on another device: How can I use MPTVOutWindow iPhone undocumented class?
one of the links in that answer says it doesn't work in iOS4+, but on a project I worked on less than one month ago, we used that feature from an iPhone4 to present, so I would challenge that (unless the developer that handled that portion used another approach)
