iOS: Digg's iOS app has been updated to include the newly launched Digg Reader. This includes the ability to import your current Google Reader feeds right into the app.
The iOS app is still new and doesn't include a lot of options, but it's a simple RSS reader that handles the import from your Google Reader account just fine. Since it's integrated into Digg's existing app, you can snag it right now through an update.
