Mark email as unread [webOS 3.x] 1
This tip is only for webOS devices running webOS 3.0 or higher
Once you open an email for reading, the email automatically gets marked as read by the TouchPad email app, and if you have an exchange or IMAP type account, this status should also get synced back to your email server. While the ability to marked that email as "unread" is buried on webOS phones in the Application dropdown menu, it's front and center (well, actually top and right) on the TouchPad app. When reading an email, just tap the "Mark as Unread" button on the top-right and the email in the listing in the middle sliding pane will turn bold to indicate it is unread and the button on the top-left will change to "Mark as Read".
