Using the Advanced Section of the Info Pane on Your iPad
Every so often, the contacts, calendars, mail accounts, or bookmarks on your iPad get so screwed up that the easiest way to fix things is to erase that information from your iPad and replace it with information from your computer.
If that’s the case, go to the Advanced section of the Info pane and click to select the Contacts or Calendars check boxes (or both). Then, the next time you sync, that information on your iPad will be replaced with the contacts or calendars from your computer.
Because the Advanced section is at the bottom of the Info pane and you have to scroll down to see it, you can easily forget that the Advanced section is there. Although you probably won’t need to use this feature very often (if ever), you’ll be happy you remembered that it’s there if you do need it.
One last thing: Check boxes in the Advanced section are disabled for items not selected. If you’re using iCloud and you want to replace any of these items on your iPad, you must first enable that item. In other words, to replace contacts or calendars you have to disable iCloud syncing before you can enable the check boxes to replace the Contacts and Calendars on this iPad.
