You might want to set up a portfolio in Yahoo! Finance with only those stocks and indexes you would want to see on your device in My Stocks. For more information about My Stocks, see How do I get stock quotes?
It's not necessary, but it's helpful to make a list of sources of business and finance news and information in your Yahoo! News and My Yahoo! pages for your account. You can edit the lists in http://news.yahoo.com and http://my.yahoo.com. Use add source and add content links to view the sources. Use further links to add and edit sources.
