Blackberry Pearl Question?

How can I set ringer ID's to incoming text messages to specific contacts. I have figured out how to set them to incoming calls but not text messages. Please help.

I downloaded the BlackBerry 8100 (Pearl) user guide and did a search under 'notification'. This is what I came up with:

Create a notification profile
1. In the profile list, click Advanced.
2. Press the Menu key.
3. Click New Profile.
4. Type a name for the profile.
5. Highlight an item.
6. Press the Menu key.
7. Click Edit.
8. Set notification options.
9. Press the Menu key.
10. Click Save.
11. To set notification options for another item, repeat steps 5 through 10.
12. Press the Menu key.
13. Click Save.
