I am guessing he means a way to delete the message on the other persons phone, much like recalling and email that has yet to be read (can do this at work). This concept would be nice as I have sent the wrong people the wrong text before when in a texting frenzy lol. I think a confirm button would be nice, confirming you want to send this text to the name of the recipient lol. I had that on my droid to prevent butt dialing.
