hey, so I have an old iphone 4 with IOS 7.1.2 on it that I wanna update to IOS 9 so I can download apps on it. Does anyone know how I can do so?
I tried downloading IPSW for IOS 9 and updating the iphone through itunes using that but it gave me an error message saying the firmware file is not compatible.
