ON THE HEELS of Irish Minister for Justice Michael McDowell's continuing reach into your phone records comes SMS 007, a perfectly legal way of encrypting your text messages. CircleTech in the Czech Republic developed the software. The one I saw needs a Series 60 Nokia phone that can run J2ME (Java) software. SMS 007 uses AES symmetric cipher and user-chosen keys to encrypt the SMS messages. The software can also encrypt a contact list that runs separately from your phone's hot key contact list.
You need SMS 007 if you do not trust the government with your text messages. SMS 007 keeps your plain text messages totally away from prying eyes--providing you don't set up SMS 007 with a simple password.
