Here are my favourite top ten BlackBerry Apps:

1. BlackBerry Messenger- Always connecting to other BlackBerry users
2. Facebook - Social networking updates and on the go
3. MSN Messenger - Connecting always
4. TwitterBerry - Always updating on the go
5. Google Maps - Locate your destination
6. ISkoot - connect Skype to your BlackBerry
7. Yahoo Messenger - Connecting always
8. WorldMate Live - Your travel companion
9. Newsweek - News on the go
10. QuickPull - Restart your blackberry without removing your battery

Rather interesting. Has few times re-read for this purpose to remember. Thanks for interesting article. Waiting for trackback
Technically Yahoo, MSN, FaceBook, and BBM are all RIM applications and not 3rd party.
10. QuickPull can be replaced by BB keyboard combination Alt+RightShift+Del keys.
6. you may consider ‘NimBuzz’ now to replace iSkoot for the Skype chatting capability. NimBuzz said to be a native BB chating tool..
