How to Sync the iPhone 4 to iTunes

1. Connect your iPhone to your computer using the USB cable that came with it. iTunes should automatically open.

2. Select your iPhone under 'Devices' on the left hand side of the iTunes window.

3. Click each of the tabs that appear on your iTunes screen, including 'Apps,' 'Music,' 'Books' and 'Photos.' Under each tab, click the buttons to select what types of content you want to sync.

4. Click 'Apply' once you are finished setting your syncing preferences.

5. Click to select the type of sync you want to perform. You will be asked whether you want to merge the data, replace the data on your iPhone or replace the data on your computer. If you choose one of the replacement options, the sync will overwrite all of the selected content on either your computer or iPhone.
