[Plugin: MobilePress] Detecting WebOS / Pre / Pixi

As a Palm Pre owner, I’d like to be able to view my iPhone theme from MP on my device but if I go to my client’s site (https://www,pattyspizza.com/) I still see the full site while iPhone users see the proper iPhone site. How can I add the Pre as a proper user agent to be detected by the plugin? Same deal with Droid’s and anything else that supports the iPhone touch themes.
