Answer 1

You must be a paid member of the iPhone Developer Program to test your software on your iPhone. Until that happens, you can only use the simulator.

Answer 2

In order to test your application on an actual device you must sign up as an iphone developer with Apple. However you can always use the iphone simulator which comes with the sdk to test your apps for free.
