The Cheezburger Network of comedy websites has released a free iPhone app (iTunes) that aggregates the images from across more than 40 sites of curated humorous content. It's a handy way to peruse the wide range of content, though the app is a little bit buggy at launch. The content displayed is limited to the images posted across sites like The Daily What, Failblog, Failbook and ROFL Razzi, and in some cases the images really need the text that accompanies them on the Web in order to make any sense. For at least The Daily What, accessing the site in mobile Safari works better. Sponsor The ad-supported app was built using mobile content management system RedFoundry.
