Hi all, long time lurker here. I was just reading up on ios 6 and one of the features trigured some memory regarding NUNCHI, which I've mostly forgotten about. Here's a bit of the copied text:

Perhaps you've noticed a theme by now: iOS 6, by and large, addresses the small things. We'd say Do Not Disturb definitely qualifies. The concept of this feature isn't new to the smartphone world, but it's one you'll use on a nightly basis -- think of how many times you've accidentally left the volume up overnight only to be rattled out of sleep because a Facebook friend wanted to invite you to use MyCalendar. With Do Not Disturb, iOS will silence all notifications as well as any calls you wish to ignore. You can tell the iPhone to allow calls from your favorites, your full contacts list (shunning numbers that are unknown to you), everybody or nobody at all. But what if it's somebody calling from an unknown number about a legitimate emergency? Enable repeated calls in the settings menu, which will allow calls from anybody who tries a second time within three minutes.

Naysayers may argue that it's easy enough to put the phone into silent mode or go through the process of turning individual notifications off, but what if there's a legitimate emergency and a loved one needs to get in touch with you right away? The option is there, and a lot of people have been asking for something like this for years.

Correct me if I'm wrong, but wasn't there a whole lot of discussion about this whole concept with regards to NUNCHI?
