Question

the code bellow works great in Simulator (both iOS 4 and 5) but adds no contact on the iOS 4 device. No error is returned. Do you have any idea why?

ABAddressBookRef ab = ABAddressBookCreate();
abGroupRef = ABAddressBookGetGroupWithRecordID(ab, 1);
ABRecordRef pRef = ABAddressBookGetPersonWithRecordID(ab, 1);
ABGroupAddMember(abGroupRef, pRef, &anError);
ABAddressBookSave(ab, &anError);

Thanks,

The problem was that the contacts were from google synced by exchange. There can be only local groups and local groups may only hold local contacts. This is kinda fair but the ABGroupAddMember should return an error if it is not going to add the member.
