How to save messages as Draft I own and Optimus One(Froyo). I want to type some couple of messages(for the same contact) and save it for sending later. How to do that?

EDIT: User wishes to save message templates that can be re-used at a later instance.
For saving drafts, GMail and Email both save drafts automatically when you leave the app or lock the phone. For SMS, it should keep any text you've entered in the text entry field until you send or delete it.
