For the first few years of its existence, syncing iPhone meant plugging it into a computer. But, with the introduction of iOS 5, you can forget the cables completely. With iOS 5, you can sync iPhone over Wi-Fi (the iPod touch and iPad, which can also run iOS 5, can also sync over Wi-Fi). Here's what you need to know to use this feature.
To use Wi-Fi syncing, you need the following:
- An iPhone, iPod touch, or iPad running iOS 5 or higher
- iTunes 10.6 or higher
- To have your iPhone and computer on the same Wi-Fi network
- Believe it or not, to sync your iPhone wirelessly, you have to begin by using wires. That's because you need to change a setting in iTunes in order to enable Wi-Fi syncing. So, to begin, plug your iPhone or iPod touch into your computer via USB in the traditional way that you'd sync your device.
- In the iPhone/iPod management screen that appears as part of the standard syncing process, you'll see the Option box towards the bottom of the screen. In that box, check the Sync with this computer over Wi-Fi button. After checking this button, click the Apply button in the bottom right corner to change that setting.
- Click the eject button (the up-facing arrow next to the device icon) next to your iPhone or iPod touch in the left-hand column in iTunes. Unplug your iPhone or iPod touch from your computer.
- With this setting changed and your iPhone no longer connected to your computer, you're ready to sync over Wi-Fi. In order to do this, though, your computer and iPhone or iPod touch will need to be connected to the same Wi-Fi network (for instance, there's no way to be on Wi-Fi at work and sync with your computer at home).
- Connect your iPhone or iPod touch to Wi-Fi.
- When that's done, tap the Settings app on your home screen. Then tap General. Scroll down to the second set of options and tap iTunes Wi-Fi Sync.
- On the iTunes Wi-Fi Sync screen, you'll see the computers you can sync your iPhone or iPod touch with, when it was last synced, and a big Sync Now button. To begin the sync, tap that button.
- The button will then change to read Cancel Sync and below it, a status message will appear. When the sync is occurring, the status message will update you on the progress of the sync and two round arrows at the top left of the screen will appear.
- Syncing iPhone using Wi-Fi is slower than via USB, so if you have a ton of content to sync, you may want to use the traditional method.
- Using Wi-Fi sync, you can sync your phone or iPod touch to more than one computer--as long as those computers are authorized with the same iTunes account.
- While the iTunes Wi-Fi Sync screen says that you need to be connected to a power source while syncing, that's not technically true. You can sync via Wi-Fi just using your device's battery. However, if your battery is low (say, less than 20%), you'll want to connect to a power source to prevent your battery from draining during the sync.
- You can't change your sync settings on your iPhone or iPod touch. That can only be done in iTunes.
