How do I delete added words from my t9 dictionary?

I havent been able to find anything about this so I'm sorry if this has already been posted.

I bought this phone from my cousin and he had a bunch of words added to his t9 dictionary that were spelled wrong because he isnt the brightest person in the world. Its really annoying when i try to text and i wanna get rid of them.

I was thinking the wipe code(*2767*3855#) would probably work but i dont want to do it if i dont have to.

I am a bit late but you can make the old word(s) move up in the list.  Let's say you have

rrn
rsn
ran

In the dictionary because you can't type good :p  Well simply go to "add word" and enter "ran" and the list will now look like this

rrn
rsn
ran

It's not the same, but you can move those other pesky words out of the way.  You can also use this to make it go straight to "home" instead of "good" and whatnot

He means it will now look like

ran
rrn
rsn

when you re enter a word into the T9 dictionary than it adds it to the top of the list again if it moved down
