We have updated the iWPhone WordPress Plugin and Theme to version 0.1.3. This is a minor release that fixes long URLs in posts that push pages wider then the iPhone/iPod touch optimized width.
We are also adding iWPhone to the oficial WordPress Plugin directory which will make it much easier to update the plugin.
We will update the install directions once the plugin is in the directory. For now you can download the plugin here. Now available in the official WordPress Plugin Directory!
