Don't want to be disturbed?
Apple's new software will give you more options for preventing messages and text notifications from disturbing you at night, for instance.
You can control how and when you get back to people. If you can't call someone back right away, you can set a reminder to call that person back later or have a text message sent directly to the caller.
There's a "call when you leave" feature that reminds you to call back when you are leaving a building or office. The phone can detect when you are leaving.
Apple's new Passbook feature will be a central place to keep your boarding passes, tickets and gift cards.
When you get to a Starbucks, for instance, the device will bring up your gift card if you have one and if you have the location feature turned on. Likewise, when you get to a movie theater or baseball stadium, the ticket will pop up. Passbook will also alert you to gate changes and flight delays once you have a boarding pass stored.
Passbook could be the foundation for a new digital commerce hub for Apple, though the iPhone 5 doesn't have a "near-field communication" chip that enables payment information to be transferred by tapping a device on a terminal at a checkout stand. A few Android phones use this technology to process payments with a feature known as Google Wallet.
