This is the required hidden gems questions for iOS 6.
Here are the rules:
- One feature per answer
- Also include how you use the feature or why it is useful
- Must be an under-documented feature. No "flag pole" features like VIP's in Mail.
Receiving iMessages sent to your phone number on multiple devices.
I know this has been raved about but it is tricky to configure and took me a while to figure out.
Steps to get this working:
When you do this, you will get notifications on the other devices confirming that is enabled.
Metallic sliders across the OS now have a subtle reflection effect that is created with the accelerometer.
You can use the Do Not Disturb setting while your iOS device is locked to silence calls, alerts, and notifications.
The setting is located at Settings > Notifications > Do Not Disturb.
Also very handy as it will silence a call but if the same person rings back within three minutes it wont silence it.
Which replace previous and next track buttons in iOS 5 and prior.
Regular songs still have next & previous track buttons. It used to be too easy to accidentally push next or previous track while trying to pause a long podcast, causing you to completely lose your place. This change both solves that problem and offers a very handy quick-rewind option.
Mail now has pull to refresh (like Twitter, Facebook, etc.). This is also now a standard control that third party developers can use. So far I've only seen this new "native" pull to refresh in Lumatics City Maps but I'm sure it'll be everywhere soon enough.
Don't like the default left to right panning direction in Camera.app's new Panorama function? Just tap the arrow and it will change from right to left!
When the app quits, the direction defaults back to left to right.
Just happened to hit the arrow yesterday by accident and saw the change. A nice feature, but for the life of me I can't figure out why it is there, other than to help the dyslexic among us (and I am one of them, so no flames, please)!
Auto-correct now considers your keyboard shortcuts when giving you suggestions and correcting your typing. In iOS 5, if you had a keyboard shortcut defined, you had to type it in exactly in order to get the substitution. iOS 6 now guesses that you meant to enter one of your shortcuts, and offers the substitution straight up even if you were going to misspell the shortcut.
Some email providers support archiving emails (most well known: Gmail). Now you have the option to archive or delete a message.
Tap-hold the delete button to access the menu options "Delete Message" and "Archieve Message".
Update: According to @Phong this does not work with Gmail.
In the new maps app, use two fingers to rotate the map. Now you can orient the map exactly in a way that makes sense. It even remembers the rotation if you rotate your device.
And even better, if you activate the compass, and then move away from your position, it remembers the rotation (previously when you moved away, it rotated back to north being up, which was very annoying).
