I heard that, there are lots of improvement and additional features in iOS 10 operating system. There are a lot of out-dated phone, which are still hanging on the older version. Some are already opted to jailbreak and others remain in official firmware. Is it possible to get iOS 10 in the lower end iPhones. On Android phone, if the device won't receive any official update anymore due to its minimum specs. The owner goes for the custom ROM that allows devices to run on latest version. Is there any such kind of supports in Apple device?
