Need to transfer settings, pictures, contacts etc from iPhone 5 to iPhone 6. The rep at the store told me to use iTunes, but I never could get it to work. Now I have new pictures etc on the new phone too, and I don't want to lose anything. Why is it that with a couple quick steps I was able to switch every single thing from my iPhone 4 to the iPhone 5, but going from the 5 to the 6 is such an ordeal??
