Did you know Blackboard has put out an iPhone app? You can use it on your iPhone or iPod Touch to check into your courses and see if there are new announcements, see if your professor has graded your work or left you comments, read recent posts on the discussion forum, and more. The app is free, so why not download it and see if it's useful?
Here's a quick YouTube video that introduces the app and shows you what it can do.
Is anyone using this app now? What do you think? Is it user-friendly? Does it help you keep up with your classes?
