Sync app info from your PC to devices with iTunes
You can use iTunes to sync the contacts, calendars and Safari bookmarks on your computer with your iPhone, iPad or iPod. iTunes also syncs this information from your device to your computer — for example, if you add contacts on your iPad and then sync your iPad to your computer, those contacts are added to your Windows address book or Outlook Express.
