My contacts on my iPhone reproduce like rabbits. I expect that they are somehow cross syncing with Outlook, iCloud, Yahoo and probably some others. In some cases, I have dozens of the same entries. I've deleted and/or linked contacts only to find that they again reproduce.
I've consulted with the "geniuses" in the Apple store (they Googled the problem!) and of course had no answer. I also spoke with Apple Support who also proved to be useless.
Does anyone have a simple or maybe not so simple solution?
