The iPhone App Developer's Sketchbook is a simple tool to help you hand-sketch your very own iPhone application. The sketchbook is a great way to quickly develop storyboard concepts for how your application is to work. The sketchbook is designed by a fellow iphone app developer, and I find it constantly useful to sketch quick ideas.
