I have had the misfortune of prematurely sending emails by inadvertently touching the "send" icon in the top right hand corner of the email touchscreen as I am composing a message. I consider this a flat out engineering failure, as an email should never be able to be sent inadvertently by a slight unconscious touch. While I haven't lost my job yet because I did so, I'd like to figure out how to avoid my messages going out by mistake because I happened to swipe the touch screen a certain way (short of going back to my old Bold).

Is there a function that requires a "yes" click before sending out an email, so that I may abort sending emails that are mistakenly set off by touching the screen?
