I'm not a BlackBerry user. But, if you are, you probably want to head to the official BlackBerry blog Inside BlackBerry to read...

BlackBerry App World: everything you wanted to know and weren't afraid to ask (Part One)

It answers the questions:

- Where do I go to get app help?
- How do apps get into the Top 25 list?
- Why is the BlackBerry App World app is itself in the Top 25 free apps list (um, duh? :-)
- I changed BlackBerry phones and can't find my apps
- Does anyone read EULAs (End User Legal Agreements)?
- Why is it memory resource hog?
