I just got my 8130 and love it. However, I think I have some unnecessary apps running in my background. First, how do I check to see what is running? Second, how do I turn the app off if it is running?
Press and hold alt, press escape and keep alt pressed. That will show what's running. Some will always show up - browser, phone, BB messenger and others. When you exit an app, hit menu and scroll to close. Best way to close.

You can not close them all... As Chaz said, Browser-BBMessenger-Call Log-Messages-Home Screen should always be open, you can close any others by Menu>Close.
