First of all, you need to open up this post in the BlackBerry browser. Tap and hold on one of the following logos, and tap the copy icon.
Once in there, you need to create the word substitution for each BlackBerry logo.

If you type something like All the cool kids are using instead of it will look like this:
This is nice and easy to show your support for BlackBerry with other BBM users or anything else you want to do to express yourself in a BlackBerry-related way.
Enjoy, and tell us how you use the BlackBerry logos!
