I've looked through many threads about customizing the text tones, but I keep seeing old threads for the 3G, I think.

They keep saying the directory for the text files is in library/audio/blahblahblahblah...

With the 3GS, there is no library/audio anything. Does anybody know where the directory is for the text sounds on the 3GS? That's what I need to know. And then if somebody could give me a tiny rundown of what to do at that point, that'd be nice, too.
