Hello. I have 2 iphone 6 phones, with 2 different apple IDs currently. One is a personal phone (phone A) and the other is for work (phone . How can I export the contacts from phone B, then import them to phone A, while keeping all of phone A's original contacts? Once that is done, I'd like to use the Apple ID that is on phone A on both phones...I just don't want to lose any contacts from either phone during this process. Is there a way in iTunes? Is there an app/program that will do this?
