First iPhone Application tutorial

With the wifi version of the iPad now available, I decided to try again to make my first iPhone app. Also, fortunately I had some extra time off from work with this being Easter weekend. So, I went over this tutorial for making a Hello World type of iPhone application. It has a bunch of stuff with gui building that seems to make it a worthwhile exercise. That is, it should be more useful than a tutorial that just displays some words on the screen. There are text boxes that take in strings, and a button that responds to tapping by displaying a message in a label control. In other words, it does some basic input and output together with event handling.
