Looks pretty awesome. You could (maybe, if this wouldn't ruin the OS's main selling point) the SMS working as a standalone application. Looks pretty nice, and looks quite a bit more secure than PSChat (sorry minizbot)
EDIT: Played with it more:
BUGS:
*If I send a message longer than the width of the screen, it gets cut off instead of continuing one line down at the left side of the screen.
*In the lock, the terminate event counts as pressing a character. Also, if I enter a password with a terminate event, it errors. (sPhone:384: attempt to concatenate string and nil)
SUGGESTIONS:
+When making an account at first bootup, it should automatically log on to SertexID instead of the player typing in the username and password twice.
+For the SMS app, add a 'contacts' menu and a 'recent' menu, as well as the logs of every chat (password protected logs, so people can't snoop)
+For SMS, add some public chatrooms.
+For the OS, give an option to allow string passwords as well as a 4-character pin.
+Try to use the Flare API! It would make polishing the menus much easier, and make animations a lot smoother.
+Speaking of polishing things up, please make the SMS chat better looking. It looks very bare and black/white.
+Try to have the SMS app on at all times, so it can alert players of any messages they get if they're not in the SMS app. Also, have it tell the player any missed messages if the player was offline when they were supposed to be received.
Good job so far!
