As the title says, is this possible? I want to "mirror" my actions on the iPhone so it shows on the computer monitor.
We've seen this on the Apple key notes, but I am not sure if this feature is public.
Many screencasts displaying an iPhone application simply use the iPhone Simulator, which is one option.
You can also take screenshots on the phone by quickly pressing the menu and the power/sleep button at the same time. The image is then saved to your "Camera Roll" and easily transferable to the computer
The other way is only possible with a Jailbroken phone - Veency is a VNC server for the iPhone, which you can connect to with a regular VNC client.
