making T9 text bigger and having trouble with picture mail.

[onoiocoko]

i have a diamond from sprint and use T9 text. when i have the work options on the top, i am required to click the right word with my fingers. this is the word in the black bar. how do i increase this font size? i know i can increase the rest of the text by spinning the wheel thing around the enter button but what about the text words.

also my picture mail doesn't really send. it takes awile and eventually is marked as sent, but it doesn't go out.

last, what file is the text and voicemail sounds in? i thought i found the right one and dropped some ringers in there but nothing. thanks
