Anyone with a 16G iPhone updated to iOS 10.3.1??? I assume you made room to update so you have the watch app. An apple genius suggested I download all my photos to the 50G I cloud data plan to free up space on my 6plus 16G phone. I had about 2,500 photos on my phone and it's probably going to take 3-4 days to complete. I already have 2.8G available space now. After that is complete I will hopefully have enough room to update the IOS so I have the watch app.
