Today is time for doing some research on predictive text input systems on Mobile phones.
I have used most mobiles phones available from different vendors. Didnt know that Nokia and others use the same algorithm (T9) but Nokia didnt use the name. Have used Motorola iTap too and found that quiet better.
Info about few systems...

BTW, Do you remember the Infinite Monkeys Theorem, there is a cool site that relates to it and actually tries to find if it can be put to use :-)
