That deals with responding to reviews of your app, not an ability to leave a review for iOS itself. Either way, I don't think the average consumer will understand that they've lost data because of a bug in a new filesystem. And if you are an app with appreciable market share and something goes wrong, I doubt one would be able to mitigate a crush of negative reviews.

haha, I knew that "actually..." was coming. I deserved that.

Whether our customers will be mollified by me replying "Actually, it's Apple's fault, you see..." remains to be seen. It has not been my experience that they're real forgiving of that kind of thing. I've been through this before.

My white knuckle grip on my chair is loosening a little though-- we might get through this bit of turbulence ok. Knock on wood. ;)
