I'm considering upgrading my iPad 3 to the Air 2 and wanted to ask a quick question to current Air 2 owners. On iPads with a mute switch, whatever function you assigned to the switch, the opposite function was an item in notification center (e.g. if you used the switch to silence the device, Control Center had a rotation lock icon). Since the Air 2 has no switch are both mute and rotation lock in CC or is it just rotation lock and you have silence with the volume buttons? If you go to Settings -> Sounds and a enable the "Change with Buttons," does that make the volume buttons essentially a silencer? I get email/text/Skype notifications a lot and when in class I used the switch to mute my iPad. Thanks!
