I hope there isn't a guy sitting somewhere who accidentally rejected the certificate :) I think that also locks everyone out. If the iPad's all crashed though it seems unlikely. Although it's definitely something that could be easily missed.
Ah, but when you read stories like this, I wouldn't trust the reporter (or even the interviewee) to be 100% accurate. "All crashed" could mean anything from a dead battery to being PIN locked to failure to launch because of an expired code signing cert :P
Good point and definitely possible. In fact I've done it myself - switched computer rejected the old certificate and suddenly nobody could access the app. Fortunately at the time it was only a few people and a beta so not too big of a problem.
