Possible to disable all notifications in iOS 5?

You seem to be missing my point. I want to be able to disable all notifications without silencing my phone, so that I can receive calls without being woken by notifications. And I don't have time to manually disable notification for each app one-by-one—and later manually enable notification for each app one-by-one—every time I take a nap.

God, this is annoying. I tried the workaround suggested to turn off cellular data and wi-fi. This almost solved the problem. But I quickly discovered that it didn't work quite the way I expected it to. I turned off data and wi-fi and went to take a nap. I was awoken by a reminder (apparently, those are activated by the iPhone, rather than pushed by the cloud). And then, when I re-enabled cellular data and wi-fi, I received an iMessage from my wife that she had sent a few minutes earlier. I had read elsewhere that SMS/MMS would go through even if data and wi-fi were turned off, but apparently that's not the case with iMessages (if someone else has experience with this, please confirm). In iOS 4, I could turn off notifications with the click of a button, in which case I would be awoken by text messages and unbothered by calendar reminders, which is exactly what I wanted. Now all I've got is a clumsy workaround that gives me the opposite result.

I read that if you plug something into the headphone jack, you'll only hear the iPhone speaker if the phone rings. I'd be interested to know whether you hear the speaker when an SMS/MMS/iMessage arrives as well (which is what I want), and in no other circumstances. Maybe I'll experiment with this after I finish my nap. If someone else knows whether this is an effective workaround, please post here.

And if anyone knows of a better workaround, please post that as well.

By the way, I've left feedback at

http://www.apple.com/feedback/iphone.html I encourage all of you to do the same.

Update: I just tested the "plug something into the headphone jack" workaround I mentioned in my last message.

The good news: The only thing that will make noise come out of the speaker seems to be an actual incoming phone call.

The bad news:

(1) Text messages will not make sound come from the iPhone speaker, with something plugged into the headphone jack. If you never want to be woken up by a text message, then this is good news for you. But I sometimes receive important text messages that I want to wake me up (along with phone calls, and nothing else). This was possible in iOS 4. In iOS 5, it seems to no longer be possible.

(2) If you plug a pair of headphones into the headphone jack for this workaround, you'll still hear sound from the headphones—it will just be very quiet. If you're a light sleeper like myself, it could still wake you up. A solution would be something that plugs into the headphone jack but does not emit noise, like an audio out cable with nothing attached to the other end. Too bad I don't have an extra one lying around. Perhaps I'll have to waste a few dollars on one just to get a semi-reasonable workaround. Still waiting for something better...
