Oh this is so sweet! I am about to set this up on about 5 NMC WordPress blogs.
The beauty of this plugin is that you upload it, optionally tweak a few settings in a WordPress settings pane, and your site is revved up for the mobile audience.
I messed about 15 minutes with the PhotoShop template and made a custom icon, which not only appears here but also becomes the default icon when I make this a bookmark on the home screen of my iPhone.
Harkening back to my rant about I’m a WordPress, You’re a Drupal I am shrugging my head because doing this equivalent process on a a drupal 5 site is going to take hours of major coding, theming, CSSing, and likely cussing.
