Self-destruct SMS

[engine]

Thousands of people have subscribed to a self-destruct text message service which started on Sunday in the UK, says the firm behind the system.
The commercial service allows sensitive messages to be destroyed 40 seconds after being read.

Amazing, now you don't need to hit delete. ;)

Hmmmm, like free proxy servers, I cannot help but wonder if this could be set up to spy on the most sensitive messages people send!

Despite the fact the message will be removed from phones, users cannot entirely avoid a data trail.

For legal reasons, a log of the message will remain on a secure server to which they have no access.

Some messages are only safe to whisper in the recipient's ear, but sometimes even that is not safe!
