Thanks, so it's sure which backend to blame for any possibly wrong behaviour

Okay. Still, I urge you to base identification on the localId of the contacts,
not their index in the list of contacts as returned by the manager, if you do
not already, as other backends pretty sure might behave differently.

"Would create" as in: would add a QContactFavorite detail with field Favorite
set to true to the *contactP, yes.
So after saving to the manager and refetching like in the code you gave, after
QContact contact2 = list2[0];
contact.detail<QContactFavorite>().isFavorite() should be true, if
contact2.localId() == contact.localId().
Is it?
