Just like Marissa Mayer promised, Yahoo has revamped its Flickr app for iOS to bring it back in line with the oh-so-social modern era. Whereas the Android app was updated back in August, the iPhone version has had only minor improvements over the last few years and was starting to look seriously dusty compared to the competition. In terms of individual features, the new app doesn't do much that various other third-party apps can't do already, but it does bunch them all into one polished package that is happy to work across multiple networks. In addition to Flickr, for instance, you can readily share your snaps with Twitter, Facebook and Tumblr. You might also dig the camera app, which separates exposure and focus points to give you more creative control over your images -- and yes, there are the obligatory filters too. The app is live on the App Store right now.
