Original icf is the default.icf in your iprontoedit software, you should be using V2.2 and it will download to your pronto by pressing File, download to ipronto. This will all take about 5 minutes through your wirless Lan. remember the ipronto must be on and not sleeping when you do this. You should get a good idea of how to do all of this by reading pp. 41 and 42 of your owners manual.
Good Luck!
