Go into profiles (your ringer settings, silent, loud, etc..), scroll down to advanced settings, in the menu select the profile you want the SMS ring tone changed in, then scroll through the different tones and select one you want, then press save, then save again, until you press save as you exit the profiles. Done. If you bounce from one profile to another, then you need to do this for each profile you use.
I am saying this from memory as I dont have my phone nearby, but I'm pretty positive I'm correct about this. Note, the Pearl and the smaller screen BB's hide the advance at the bottom of the pop-up screen so scroll down to see it.
