I have the same question.
When Facebook syncs with its own group of contacts on an iOS device, it seems that linking contacts with e.g. Their iCloud or a gmail exchange counterpart on the device is the only way forth to "integrate" facebook informations with existing contacts (on an iOS device).
Or is it? At least the Facebook integration does not seem to update on existing groups of contacts, but instead uses its own group.
Another question: when (manually) having linked an existing contact with the now new Facebook counterpart, there is an option to choose a profile picture.
Again, manually, you can choose e.g. Facebook profile picture.
I guess this is what most people aim for; could this not be automated?
Again, this even does not sync to other iOS devices. So like the beginning of this thread; no infos within linked contacts seem to be synced across devices.
So it seems, that a lot of Facebook integration into contacts ends up with a lot of manual work on each iOS device you might own?
Any suggestions or solutions on more effectively automating facebook integration into contacts in iOS 6?
Before iOS 6 I used a 3rd party app which seemlessly synced facebook profile pictures and birthdays directly into existing contacts, which that way synced in its normal way via services used (gmail / icloud). But in iOS 6 it seems that facebook contacts get their own "group" in contacts, that you manually need to link to existing contacts?
