Your iPhone has a lot in common with a computer. It can edit documents, install new programs, share files, browse the Internet, and perform numerous other functions that let you get work done and keep yourself entertained. Like a computer, the iPhone needs a framework that enables you to use all of these features. This is called an operating system. If you have a PC at home or work, then it is likely running some version of Windows. Windows XP, Vista, 7, 8 or 10 is the operating system for the computer, where iOS is the operating system for your iPhone.
Different versions of iOS have different sets of features, and the method for changing something in one iOS version might be different than that method in a different iOS version. If you are trying to troubleshoot an issue and a technician asks you for your iOS version, then you can follow the steps below to see how you can find it.
