BlackBerry app: TheStreet

This is a handy app for keeping an eye on the markets and your stock portfolio, as well as the latest business news. You can personalize your news preferences and your stocks to watch, and have updates pushed automatically to your handheld. You also get notification of analyst upgrades and downgrades, columns from commentators such as Jim “Mad Money” Cramer, and your home screen icon will light-up to inform you of new content.
