Beginning preliminaries for this, doing research (very special thanks to Antonio Lupetti for his STUpendous article, “Best Practices To Develop Perfect Websites for iPhone and Mobile Devices!!) My Japanese pop-culture site, Jpopexpress.com, has a mobile functionality (which uses Google Reader), but certainly an independent, standalone mobile-optimized version of your website would be superior (and in addition, provide you with more distance from the “proprietary monopolies,” something that I have been increasingly focusing on lately 
).
[Oh, and FYI: just in case you didn't know already, dimensions for the iPhone screen are 320w x 480h ]
