A high-quality news source, complete with live video
Many publications have their own dedicated BlackBerry app, but so far my favorite has been Al Jazeera.
It has a great finger-friendly interface with large images for each story, links to live video and audio feeds, plus an easily accessible navigation menu to a wide range of subject matter. Stories themselves have share menus readily accessible, support in-line video, and a favoriting system for future reference. If you’re looking for professional world news, this is a great place to start.
