Dropbox has released version 2.0 of Mailbox for iPhone, iPad, and iPod touch. Mailbox is the popular email application that allows users to easily sort email for later access. In line with announcements from Dropbox’s recent press conference, the update adds a feature called Auto-swipe. This feature essentially automates common actions based on user’s past email email swipe and snooze tendencies. Mailbox is also leveraging Dropbox’s backend to synchronize the app’s settings across devices.
