Around September 1, 2016 just weeks prior to the release of the iPhone 7, I sold my iPhone 6 and purposefully downgraded to an old iPhone 4 I had sitting in the closet. My intentions were to use the iPhone 4 for a few weeks and then buy the iPhone 7 when it came out. Well, after being lazy for a while a few weeks became a few months, and yes. Finally, I have the new iPhone 7. Here is my dilemma. I made a backup file of my old iPhone 6 on Sep 1, 2016. The bad news is that I used the iPhone 4 for September through December without putting any contacts or backup file on it. Today, I can restore to the new iPhone 7 everything that was on the iPhone 6 backup file saved on Sep 1, 2016. My question is... After restoring the Sep 1, 2016 backup file to the new iPhone, how can I add another backup file from Sep through Dec to my new iPhone 7??? Basically, in a nutshell I have the new iPhone 7. I need to... 1) Restore an iPhone 6 backup file that was made on Sep 1, 2016 2) Add an iPhone 4 backup file for everything from Sep - Dec 2016. IS THIS POSSIBLE???
