First, from the home screen, select Personal Email Setup-->Email Accounts and then for the account you're ready to part with, simply select "delete." You'll be prompted to confirm your desire.
After completing the task, that account will no longer sync with your BlackBerry and you will no longer see an icon for it on your home screen.
If rather than deleting an account, you'd like to change the settings, go to the same screen (home screen, select Personal Email Setup-->Email Accounts) and click on Edit for the particular account.
Be sure to press the Menu button and click "save" after making changes (or say "yes" when you are prompted to while exiting).
