BIO.ID. is fun program for Windows Mobile phones. It displays (simulated)  user identification gateway, eye iris, fingerprint, or voice in order to check the incoming text message (SMS).

BIO.ID can replace your incoming text message notification alert with a cool simulation  with much better audio-visual effects. An unique new function added: every message marked as Read in Inbox, will "self-destruct" in the specified time. This will move such message to Delete Items folder (as usually), or delete it completely and invisible.
