I recently upgraded to iTunes 184.108.40.206. When I plug my iPhone 4 (iOS 5.1.1) into the computer, I noticed that under the "Info" tab, "Sync Contacts" and "Sync Calendars" don't have any options displayed, and it give me the message:
Your contacts (calendars) are being synced with your iPhone over the air from iCloud.
Over-the-air sync settings can be changed on your iPhone.
However, I do not know how to change those settings on my iPhone. What settings should I change to enable me to sync Contacts and Calendars through iTunes once again?
