I use BlackBoard in my daily life and am not on a "Sprint" network. I knew Xeudoxus over at DroidForums already had fixed this issue but he is taking a break. I simply took his work and added it to the newer 2.4.2 version. All kudos goes to him. I have Verizon and I know it works on that network, if you are on another please feel free to try.
