I used to have the edit button in the photo app missing back in my iPhone 4S. When I used to enable the photostream as has been suggested to me, the edit button is back again. And as soon as I turn off the photostream in icloud, the edit tool vanishes again! Now people here asked me restore my iPhone. I actually bought an iPhone 5 and restore all my data to it, I noticed that I am facing yet the same problem which is the missing of the edit button in photo app. And more surprisingly, the edit problem in iPhone 4S when I set it as a new phone is okay and seems nothing wrong with it. I just can’t erase all data in my iPhone 5 now nor get this problem to be solved. So please any help will be highly appreciated.
