The BlackBerry Web browser is the default browser for all BlackBerry devices. It features tabbed browsing, the ability to pinch and zoom for touch-screen models and an option to automatically adjust the font size for text-heavy websites. The browser is included as a component of the core operating system. Therefore, browser updates are tied to operating system updates and not available as a separate download.
