I’ve submitted the official I Can Has Cheezburger iphone app to the app store. Hopefully it will be approved. I also removed the original LOLcats from sale, to avoid any confusion.
Unlike the original LOLCats, which searched Flickr for public photos, the new app uses RSS feeds from I Can Has Cheezburger and related sites, including FAILblog, Engrish Funny, and ROFLrazzi. It also has some user interface refinements, like a navigation bar that hides when you tap the screen.
