November 9, 2008. I've updated my template to include the 3G iPhone and to support better layering on individual slides. Now available on its own page.Blake Burris reminded me that during iPhoneDevCamp I had created a simple Keynote template for laying out flows for iPhone apps, similar to the approach I took in developing exPhone using a Keynote document to do the basic wireframing and page layout design. Four states come with this template, and can be seen in the figure above. Go ahead and download it and lemme know what you think -- if this is useful. And, of course, you'll need Keynote to make use of this.
