Either make them/find them and replace the default sounds with those via SSH or you can look at ToneFX. You can create your own tones and upload them into your phone that way.
you know if i'm not mistaken, i know i saw a new cydia app load this morning that had the new SMS tones from 4.2.1. otherwise, yes BiteSMS (i think a full lisence is on sale for ~$7 until Xmas) has custom tones.

just wanted to say thanks for the recommendations, all. I was using tlert before in order to have quick replies to SMS messages, but the default bitesms quick-reply is even better. I got rid of tlert, and now i've switched over to bitesms. Thanks!
