I have an iPhone 4 which I have been told can update to iOS 7. But if I do, what will happen?
Will any of my apps be deleted or start over or something? Because I have this free music app-NOT illegal-that has all my music on it and I don't want it all deleted.
What about my pictures? Do I have to back them up first? What about my apps WITH pictures?
Notes? Calendar? Will it completely start over?
Will my apps be arranged the same or not? I NEED All THE INFO I CAN GET!
(Optional) can you please tell me how to update? I heard something about connecting it to the computer and updating the AppStore first?
