A couple of years ago, Virgin Mobile began allowing users to lock certain phone numbers at night to prevent themselves from drunk dialing (http://www.engadget.com/2004/11/30/virgin-mobile-wants-to-help-stop-you-from-drunk-dialing/). That's a great idea, but it still left the opportunity for drunk dialers to get their message across via text'ing with equally awkward and embarrasing results. Yes ladies and gentlemen, the drunk text message, the slack-jawed cousin of the drunk dial, has matured into a fairly regular casualty of drinking. Those who text regularly have most certainly received one or worse, have been guilty of sending one. Not they'd even remember.
Now, Samusng has been developed a technology that will allow a user to delete a text message that hasn't been read.
(From http://www.realtechnews.com/posts/1471) -->
"Samsung has been awarded a patent on a method of sending an SMS to a handset then being able to later send a “delete” command to the same phone to erase the SMS from the handset memory. The patent is apparently aimed at people who mass broadcast messages and accidentally include incorrect people in the mailing list. We obviously can think of more probable uses for the technology - such as quickly erasing those embarrassing messages you sent the night before when rather drunk."
This is reminiscent of the unsend email function that AOL had back in the day (I don't know if it still exists).
Now the only question is can you sober up in time to unsend before it's read?
