Yes. ABAddressBook is what you want.

Looks like it:

ABAddressBookRef addressBook = ABAddressBookCreate();
CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeople(addressBook);
CFIndex nPeople = ABAddressBookGetPersonCount(addressBook);

for( int i = 0 ; i < nPeople ; i++ ) {
  ABRecordRef ref = CFArrayGetValueAtIndex(allPeople, i );
  NSLog(@"inside loop");
}
