Hey All I have an iPhone 6 with iOS 8.4.1. I am planing to sell it before iPhone 6S gets announced. But i am afraid if i sell my 6 now and will try to use my backup from 8.4.1 to iOS 9, it won't let me restore it. Is that true? can someone come with a solution? or should i just hold on and miss few bucks and buy the new one first and then sell the old one?
