iPhone 4S does not vibrate when new mail is received  when "New Mail" sound is set to "none" - *even* if "Vibrate" is set to "on" and "Silent Vibrate" is set to "on".

I've hunted high and low for an answer to this question, but cannot find an answer, so I'm hoping someone here can help me out.

My new iPhone 4S will not vibrate when new mail is received when I have the "New Mail" sound set to "none" - even if I have both "Vibrate" and "Silent Vibrate" set to "yes", and regardless if I have the left toggle switch set to sounds or vibrate.

This didn't use to be the behavior in IOS4 and lower, and I just want to make sure it's the expected behavior in IO5 before I start wondering if I might have a defective device.

What I want to be able to do, and what I thought I used to be able to do, is set the phone so no sounds are played when mail arrives but that the phone vibrates, but it won't vibrate unless I have a sound selected. Now, obviously, I can put my phone in silent mode and it will vibrate when mail is received, but I want to have sounds enabled for calls and voicemail - just not email. But I do want the phone to vibrate in all cases.

Am I missing something here?

Pics attached.
