I cant believe they are giving this beautiful iPhone theme away. Its super simple to install, just upload it as a plug in and activate. It detects when you are on an iPhone and displays your Wordpress blog like a native iPhone app. 

Now if your a designer then you will not be happy with the basic design. No problem, just edit the image and CSS files to  make it your own. It comes with starter icons but you can add your own. 

Couple this with the iPhone admin theme and you are a mobile blogging master.
