Apple introduced iOS 11 to the world at its WWDC 2017 keynote. Following the event Apple has released several betas and public beta versions. And finally, Apple officially releases iOS 11 on Tuesday, September 19.Before you go ahead to download and install iOS 11 on your iPhone or iPad, there are a few things you should consider before you start the installation process.
As you are going to install a major update on your iDevice, it could be unstable and you may lose some data. Therefore, it is very important to back up everything beforehand in order to restore back to an earlier stable version when needed. You can either use iTunes or iCloud to do this. Or you can selectively back up important files using third-party software Tenorshare iCareFone.
If you’d like to install over-the-air (OTV), you’ll need to make sure there is enough available space on your iPhone, iPad or iPod touch. We suggest that you free up at least 2GB space for the new iOS so that everything goes smoothly.
