Submission + - Can T9 predictive texting be improved upon?

Sam Haine '95 writes: I'm being driven slowly mad by the inefficiency of predictive texting on my mobile phone. There must be a more efficient way of grouping the letters on the numeric keypad, but the only way I can think of finding it is a brute force approach which involves trying 8^26 combinations! Is there a smarter way of finding the grouping of letters with the fewest textonyms? I'm assuming an English language dictionary and yes, I am aware of phones with QWERTY keyboards!
