Everyday I get hundreds of emails, now, some of these emails are just updates and things I don't need to read. I spend a lot of time looking through emails and tapping them so the red badge would go away. This tweak allows me to tap two buttons and all of my emails will be marked as read. This is the perfect tweak for anyone who has separated email inbox's and one is there for spam or something that you don't really need to read.You can find "Mark Read" in Cydia.
