Before we start the steps, you need download iTunes
to your computer. If you already have iTunes, you need to make sure you update it to at least version or it won't recognize your iPad 3. You'll need it once you get everything synced with iTunes.
Step 1: Connect your iPad 3 to your computer using the USB that comes with the device. Your iPad 3 will be detected automatically and set up will begin.
Step 2: Pick "Register Later" on the Welcome screen and agreeing to the user agreement. Then log on to your iTunes account and then the iTunes will show welcome to your new iPad as show below.
Step 3: At this time, select "Set up as a new iPad" and continue. Then you will come to a place that you have to start making some decisions. Here you can selectively sync your apps and media. Media is best synced manually, for the space issues we mentioned above. You can autofill songs from playlists, or drag them in one by one from your iTunes library.
Once you’re all set up, you can disconnect your device and move over to the Settings menu, where you can set up wallpaper options. And that’s it.
Let me know if that is the information you needed.
