This article explains how to sync iPhone over Wi-Fi. Information in this article applies to iPhones and other iOS devices running iOS 5 or higher and a computer running iTunes 10.6 or higher.
To sync your iPhone wirelessly, you need to use a cable—at least once—to change a setting in iTunes to enable wireless syncing for your phone. Do this one time, and you can go wireless every time afterward.
After the setting is changed and the iPhone is disconnected from the computer, you’re ready to sync over Wi-Fi. You’ll never need to change that setting on the computer again.
Follow these steps to sync:
Syncing an iPhone wirelessly is slower than doing it with USB. If you have a ton of content to sync, use the traditional wired method.
You don’t have to remember to sync manually. When an iPhone is connected to a power source and is on the same Wi-Fi network as the computer, the phone syncs automatically.
Using Wi-Fi sync, you can sync a phone or iPod Touch to more than one computer, as long as those computers are authorized with the same Apple ID.
You can’t change the sync settings on an iPhone or iPod Touch. That can only be done in iTunes.
If there are problems syncing the iPhone over Wi-Fi, try these fixes:
You don’t have to sync with a computer or iTunes at all. If you want, sync the data on the iPhone to iCloud. Some people prefer this option. For others who don’t have computers, it’s the only choice.
