I've got a few iPads in my arsenal for development testing, but they're all tied up for the next 2 weeks or so. I've only got my personal iPad available until then, and I'd rather not use my personal one for iOS 6 development if it's going to break BA. I'll take one for the team and find out myself if I have to, but I figured I'd throw it out there in case anyone else has experience with the matter.
The sooner I find out, the more time I'll have to squeeze a loaner out of a friend of mine if iOS 6 + BA don't work quite right.
