So I'm just wondering if this is possible, that when typing a text message perhaps adding a second button or something, it would be possible to pull up the phone keypad, and type a short message in say word or t9 whatever sprint / palm uses for their such typing.

First of all, is it possible to directly edit the sms/chat app like this? and secondly does the pre have one of these dictionarys?

Thanks for any ideas, i have minor coding expirence, but would love to learn and try and develop this if its possible, i'm rather new to the... possibilites of the pre
