Is there is any notification passed after an update or change in a contacts Address Book information in iOS?

Use ABAddressBookRegisterExternalChangeCallback to listen to updates in the Address Book.

You may also listen to the @"ABCDataBaseChangedExternallyNotification" notification, or even deeper, the "__ABDataBaseChangedByOtherProcessNotification" Darwin notification, but these are all undocumented. Don't rely on them. ABAddressBookRegisterExternalChangeCallback is perfectly fine.
