And now, someone's cooked up an iPhone version of that same plugin, where you simply install the WP plugin on your blog (for WordPress 2.2.1), and instantly you can see all your posts formatted specifically for the iPhone. Instead of creating a whole other, "mobile" version of your site, you can simply put in this plugin, and you can get a link that will reformat your content for the iPhone or iPod touch. Very excellent.
If you run a WordPress blog or site and were thinking about creating a version of it for the iPhone or iPod touch, your work is done. Download the iWPhone plugin from Content.Robot, install it, and you're set.
