Is it possible to send some1 a spoofed SMS so that they think that it has been sent from some1 else. For example like a fake email. Could u telnet to 1 of these sites on the net that allow you to send free SMS's and then construct ur own header for the sms packet. By construction the header u can alter the senders number and i know there are fields in the header to allow for the recieving of reports on delievery. Has Ne1 gotta clue as 2 how this is done?

Cos then it will mean that the validility of a SMS will be greatly reduced.
