There are many ways that you could proceed to carrying out your iOS update but it would really be helpful for you to refer to websites that provide useful information and tutorials on every possible option available out there for you to upgrade your device’s operating system. The iOS has existed for a while and numerous changes have been implemented but this is a completely new era with consumers being aware of all of their options.
Since no one appreciates restrictions of any kind when it comes to using a device that they have paid for, it only makes sense for Apple to ensure the restrictions they used to impose in the past are lifted otherwise they would risk seeing huge drop in sales which is already the case. Customers have all the freedom with android and there are devices which compete with Apple’s iPhone and iPads which people can easily go for.
Their loyalty to Apple should not really be taken for granted by restricting them to what they can and cannot do lest it should prove to be a reason for them to move over to alternative device brands. I think Apple has already realized this and the new iOS Update is expected to make things easier for loyal Apple users. So, get a good website that would provide you with every bit of information on upgrading and using the new iOS version to your satisfaction.
