So, no one has talked about this as far as I have been able to tell. Do we need to unfair our watches from our iPhones tonight so they back up to the phone and then have the phone back up as well? I will be trading in my iPhone 6+ as part of the IUP tomorrow and won't be able to do this after the fact. It is my understanding that if you forget to unpair the watch and have the backup saved then you will lose all the data on the watch? Or am I way off on this?
