Basically it's this:

• Click on Edit at the top right of the screen while in the email app
• Check the first email item
• Hold down the move button at the bottom of the screen, and at the same deselect the the email you just selected (yeah, you gotta use your other hand) and then let go of the move button
• A new window appears and allows you to move all your email messages to trash!
