WordPress.com doesn’t give you simple instructions on how to install the Press This bookmark on to the iPhone and iPad safari bookmark bar. I found this cool little tool that helps you install all the different bookmarklets available on the internet straight from your idevice. Thanks to Yusuke Kawasaki! http://kawanet.blogspot.com/2010/08/bookmarklet-viewer-bookmarklet-for.html

Install his bookmarklet, then visit the Tools page on your wordpress admin dashboard, to easily install the Press This bookmarklet using the same method. Let me know if you need any help!
