Here is a list of my favorite BlackBerry applications, and the links for where to get them:

Google IM.

Check your Google email with this BlackBerry application.
Viigo Free

I personally prefer this over BlackBerry Maps. Nicer UI, My Location, turn by turn directions with satellite/map views, and also has voice search capability.

Control your BlackBerry with your voice with this easy to use application. No more texting while driving (not that you should be anyway π ), with this you can send a text, email, or open certain applications with your voice alone.
Instango Free
Fast, free, and reliable IM application. Currently still in beta, but a really good application nonetheless.
