iPhones run on an operating system, and each time a new iPhone is released, the OS is upgraded and the number is changed. It's important to know which iPhone you have to learn more about available features. It's also important to know what iPhone you have if you need to contact customer service, or if you are looking for accessories or replacement parts. The OS number can be found on your iPhone, or through iTunes by hooking up to your computer.
