One of the worst things about syncing your iOS device was that you were constantly having to plug in your device to you computer. Not anymore. Now, if your computer and iOS device are both on the same Wi-Fi network, you can sync all your applications, books, movies, tv shows, music, podcast, audiobooks, ringtones and photos without plugging any wires in.
Well, I lied when I said you didn’t have to connect your device by wire again, because in order to enable wireless syncing you have to connect your device via wire one last time. Plug in your device and go to the source list in iTunes, then scroll down to the summary pane. Your iOS device can’t sync with iTunes when iTunes isn’t running, so you’ll need to check two boxes in the options section. Check both, Open iTunes when this iPad (or iPhone/iPod) is connected, and Sync with this iPad (or iPhone/iPod) Over Wi-Fi. Once both are checked, simply press the sync button to save your changes.
There are two ways to get your device to sync now, one is by going to the Settings app on your device and tapping General > iTunes Wi-Fi Sync then Sync Now, which will simply start syncing right away. The other way is to have it automatically sync whenever you plug your device in to charge. For instance, when I go to bed, I plug my iPhone and iPad in on my nightstand, when I do that it automatically sync with my iTunes, I don’t even have to think about it. It’s pretty much a simple setup that you only have to do once for each of your devices and then just forget about it and let it do all the work.
If you open up iTunes while your device is wireless connected, you can still change the settings and select media to sync. To get to the connected devices, click the devices button on the upper right hand side of the iTunes. If you have more than one device connected, they will all show up in the little devices pane. Select the one you’d like to go to and you can select or de-select media to sync, as well as change options that will all wirelessly sync to your device.
