I, too, have had my APPLE system double (even triple once) my contacts. And I have 2816 cards right now (which is a double batch, so really about have of that.). I have searched EVERYWHERE and wasted over an hour with Apple on the phone to find out if this merge only merges the 'top essential' data or DOES IT INCLUDE THE CONTACTS NOTES SECTION. I have LOTS of need info in the Notes section and not a single Senior Advisor could answer that question! Anyone here? NO GUESSES PLEASE. Only hardcore KNOWING! Thanks!
