Swype and T9: Common ciphers

Every time we use our cell phones to text, most of us us a cipher. Especially for those of us who use Swype or T9. In both of these forms of texting, numbers on the phone represent letters. With Swype, you simply run your fingers along the touch screen on top of where the letters are and the phone analyzes the motion you made to determine the word you were trying to spell. I still think that Swype is an insane idea because the phone has to convert a simple motion of your finger into words. Both of these methods of texting demonstrate the phones ability to convert numbers or symbols into competent words. I just never really saw these as ciphers before but they actually make sense as ciphers.
