Couple of updates for those who like their Digg on the go. First up is the revamp of the social news aggregator's iOS app. Using the latest version, you can view stories by unread items only and delete feeds from directly within the app. Scrolling has been improved as well, and the offering now has support for Readability. Digg Reader's getting a boost as well, with optimization on the mobile site "captur[ing] the look and feel" of the iOS app, according to Digg. There's also full support for sites like YouTube and SoundCloud via HTML5. More info can be excavated in the source link below.
