I want to have a different ringtone for texting and a different one for calls. How do I do this on my Blackberry Pearl?

I’m trying to figure out the same thing!

I figured it out
Well first set your regular calls tone, then to set your text:
1. Profiles
2. Scroll to and click on advanced
3. Click on Normal (Active) [it should be in bold]
4. Scroll to SMS Text and click
5. Change ringtone and save!
