I updated my iphone yesterday.  I have the 4S.  I have my daughters and mine contacts now.  I don't want hers.  How did that happen and how do I get rid of them?

Answer 1

This happens with you are both syncing data such as contacts on your devices with the same iCloud account.  This will result in the data being merged and synced back to all connected devices.  To correct this you need to have different iCloud accounts on each device.
To do this, on the device that will be changing iCloud accounts go to Settings>iCloud and turn all data that is syncing with iCloud (contacts, calendars, etc.) to Off.  When prompted choose to keep the data on the iPhone.  After everything is turned off, scroll to the bottom and tap Delete Account.  (This will only delete the account from the phone, not from iCloud, so the other phone won't be effected by this.)  Next, set up a new iCloud account using a different ID, then turn data syncing for contacts, etc. back to On.  When prompted, choose Merge.  This will upload the data to your new account.  At this point you will have two separate iCloud accounts on each phone with identical data.
Next, you'll have to go to icloud.com on your computer and sign into each iCloud account separately and delete the unwanted data (for example, deleting her contacts from your iCloud account and vice versa).  These changes will be reflected on each device and things should now be fixed.
