iPhone Photoshop Prototyping Template

At the Voices That Matter 2009 iPhone developer conference there was a heavy emphasis on good design and August Trometer suggested using paper templates or whatever we could do to plot out or applications before diving into development. We even got an iPhone Sketchbook as a goodie from the conference, which is a neat notepad of grid paper with a 1:1 blank iPhone in the middle of the page. I googled around the web and found a nice photoshop template for this at http://www.teehanlax.com/blog/?p=1628. I’ve not tried it yet, but it looks like a promising way to get a more real representation of your final design.
