Ever wake up with an inbox full of Twitter or Facebook emails? Annoyed by newsletters you’re not going to read anyway? Going through them one by one just to get rid of the red badge takes too much time. How annoying! Thanks to the developers of YourTube 2, YourTube HD and Safari Download Manager, they invented Mark Read, a tweak that can easily mark either your entire inbox or just the emails you want as read/unread, right within Mail.app.
Simply tap “Edit” in your mailbox, then select the emails you want to mark as read/unread and tap “Mark” in the upper left corner. If you want to mark the entire mailbox as read/unread, tap “Mark All”.
Mark Read is available in the Cydia Store via BigBoss repository for $1.99
