John Cook at Skeptical Science has worked on an iPhone app (free) that provides a wealth of double-skepticism (skepticism about the skepticism). It's a great consolidation of the arguments, and a wonderful example of how apps can find a very specific role to play in public discourse.

Brett Anderson of Accuweather writes briefly about the app in his blog. He mentions that he doesn't have an iPhone (shame, shame!) and hasn't seen it, so here are some screenshots.

The app was written by Shine Technologies. Only minor quibble is the icon for the rumors (an ear). At first glance, it suggested to me that these were audio clips; they're actually text which is great.

I've attached several screenshots showing the sequence of using this app. It's great!
