Replying to an iMessage (or SMS or MMS) is only one of several things you can do with the iPhone, iPod touch, iPad, and Mac Messages app. You can also copy it, forward it, or delete it altogether. Copying an iMessage is a great way to move important information to other apps, like Mail or Notes or for searching in Safari. Forwarding is a super fast way to share one person's iMessage with another. And deleting, if you've received something personal in a text -- or sext, we don't judge! -- is the perfect way to maintain your privacy.
