A new version of Instapaper, 3.0, is now on sale at the App Store. The title lets users bookmark and download converted webpages for later reading. The v3.0 update more deeply integrates sharing via Twitter, Facebook, Tumblr, Pinboard and Evernote. Preferences and credentials sync between the app and the Instapaper website; sharing commands can be queued offline for execution when a connection becomes available.
