The phone starts guessing with the first number:
And so on. It does a rather good job, too. Though it feels odd: you almost HAVE to not look at the screen as you type, and he you make a mistake the result is not a misspelled word but the wrong word spelled right. Definitely requires ignoring some familiar habits.
