im sort of confused. if i download the new version of the iphone sdk and i want to run lunar lander, one of the apple provided applications, can i do that with my iphone plugged in?
The only way that you would be able to run the application on your phone would be to register with the iPhone developer program, wait for apple to accept you and then install on the phone. If you don't want to do this you're stuck using the simulator that comes with the SDK
