Congratulations to Blackboard for releasing their first mobile learning app. This is further indication that there is definitely movement in the direction of mobile for learning. (Desire2Learn had already released 2GO for use with the BlackBerry.)
I did download the Blackboard application on an iPhone, but don't have a BlackBoard account so can't really test it. The comments in the Apple App Store are quite negative. Have you tried it? If so, what is your reaction?
