If Wi-Fi syncing with iTunes is something you still want to do, you're going to have to plug in your iPhone/iPad at some point and enable Wi-Fi syncing under the summary tab. Once you've done that, your device's avatar will still show in the iTunes sidebar, even after you unplug it. Click on the avatar and use the different tabs to select which apps, movies, TV shows, songs, books and podcasts to copy. After making your changes, click Apply and Sync in the lower right-hand corner of the iTunes window. When you plug your iPhone in at night, it will automatically connect with the iTunes computer -- as long as both are on the same Wi-Fi network -- and sync up any changes. (This usually happens after the iCloud backup is complete.)
A better way to decline calls
Although the updated Phone app looks the same, save for the new Keypad, which gets a lighter color scheme, there are welcome changes. The biggest involves how you decline a phone call. In iOS 5, a swipe across the iPhone's lock screen answered a call, and a button located at the top of the screen dismissed it. For many, myself included, hitting that button made it easy to forgot a call ever took place.
In iOS 6, there's a new option to slide the on-screen phone icon vertically, revealing two actions: Remind Me Later and Reply With Message. Selecting either gives you even more options, such as location- and time-based reminders under the Remind Me Later button and a couple of quick responses available under Reply With Messages. You can edit the quick response messages under Settings> Phone> Reply with Message, or you can manually type a response.
It's amazing how much impact this simple change can make, allowing me to be much more diligent in returning phone calls.
There may be times when you don't want to answer your phone at all and Apple has you covered there, too. iOS 6 features a new system-wide Do No Disturb feature that can be manually turned on or set to activate during customizable hours.
The new Do No Disturb option blocks all calls and notifications, stopping your iPhone from lighting up in the middle of the night with alerts and unwanted calls.
Do No Disturb does just that: blocks all calls and notifications, which effectively puts an end to your phone lighting up in the middle of the night for alerts and unwanted calls. You can also create a custom group of people whose calls are allowed to go through no matter what, even if Do Not Disturb is on. There's even a setting that allows a call to get through if the same phone number calls more than once within a three-minute time span. That's designed to help a caller connect in case of an emergency. Do Not Disturb can be activated through a toggle in the Settings app; specific preferences can be modified in Settings>Notifications>Do Not Disturb.
