Q: How to prevent contacts mix-up between two iPhones?

An old iPhone 4 was given from a daughter to her mother after the daughter got a new updated iPhone.  The old iPhone 4 had been reset and cleaned, i.e. no data whatsoever was found.  The old iPhone 4 now also has a different Apple ID.  New contacts of the mother had all been entered into the old iPhone 4.  For some reason, the old iPhone 4 some time later has somehow got the daughter's contacts as well.  They are all mixed together.  Is it because the daughter's iPhone data has been backed up to the Apple server and from there the daughter's contacts were downloaded automatcially to her old iPhone 4 which now has a different Apple ID.

 

 

How could one completely dissociate two iPhones which had once been owned by one and the same person?

iPhone 4, iOS 7.1.2

    Is it possible not to follow the steps and erase all the data to achieve the same effect?  I remember the phone was blank like a brand-new phone when the phone was handed over.

     

    Only thing it hadn't been done was the phone still linked to daughter's Apple ID.  So I simply changed the password but kept the email address, because I didn't know how to dissociate the phone from the then set email address or Apple ID at the time.  I didn't know this particular step was necessary at the time anyway.  Later on I was told the daughter has some problem with her new phone, so then I changed the email address altogether.  So I suppose the Applie ID has been changed.

    I suspect that the phone is still signed in to the daughter's Apple ID in Settings > iCloud and/or Settings > Mail, Contacts, Calendars > Accounts.

    Thanks!  I will check when I can get hold of the phone again.
