In case anyone cares, I fixed my BlackBerry by using the instructions found here: http://www.blackberryforums.com/rim-software/67224-remove-policy.html.
I found a couple of other places/posts with instructions on how to apply a new, "blank" policy, but this post seemed to have the only policy.bin that allowed "split-pipe" connections, which is what seemed to be the problem.
FYI, disabling the bbproblem@rorywohl.us email address, so don't bother trying to spam it.
