WhatTheFont Now on iPhone

The “WhatTheFont” feature at www.MyFonts.com attempts to identify a font from a sample image you upload, and it’s almost always successful. 

Now, they have a free iPhone app  that lets you snap a photo of some text (from directly within the app), and upload it for identification. The identified font can then be explored in Safari on your iPhone, or the app can email a URL to you for later exploration. It also works with photos saved in your iPhoto library, in case you want to “snap now and process later”.
