Add unread message folder, attachment folder to iOS Mail

Mail for iOS includes your inbox, flagged messages, and VIP folders by default, but you can easily add a folder that displays just your unread messages or messages with attachments.To choose which mailboxes show, go to your mailboxes list (if you're in your inbox tap the "< Mailboxes" button in the top left corner). Tap the "Edit" button in the top right corner and put a checkmark next to each item you want to show. Tap the "Done" button.
