Digg has updated its iOS app, bringing the promised integration of its Google Reader replacement to the iPhone and iPad. Digg first announced that it would be adding an RSS reader to its app a month ago, promising similar functionality to Google Reader along with an API. The app also includes a Google Reader import feature that can automatically import all of a user's feeds and folders directly into the Digg app. Digg is a free download in the App Store and offers support for both the iPhone and iPad.
