If you are developing for iOS 5.0 or later then use following methods:

CFArrayRef ABPersonCreatePeopleInSourceWithVCardRepresentation ( ABRecordRef source, CFDataRef vCardData )

CFArrayRef ABPersonCreateVCardRepresentationWithPeople ( CFArrayRef people )

And documentation is here : http://developer.apple.com/library/ios/#documentation/AddressBook/Reference/ABPersonRef_iPhoneOS/Reference/reference.html

Note:- Reading documentation carefully will help you a lot to develop entire project.
