Book excerpt: The latest iPhone models were released on September 19th in the United States and the United Kingdom, and according to Apple, are the “biggest advancements in iPhone history.” It’s a clever play on words, as the new models both sport much larger screens than the iPhones of yesteryear. Whereas the iPhone 4S and below had a meager 3.5 inch screen (considered generous at the time), the iPhone 5, 5S and 5C were stretched out to 4 inches. Faced with stiff competition from Android flagships that have long featured big screens, the iPhone 6 and 6 Plus are Apple’s authoritative answer to the growing number of iOS fans restlessly awaiting their own big phones. The new phones are powered behind the scenes by Apple’s latest software release, iOS 8, which also brings many features and changes with it. This guide is designed to walk you through the most important parts of the phone, from the basics and learning how to navigate through the phone, to more advanced features like setting up email accounts and understanding what the cloud really is. Towards the end, a list of the 20 top paid and free applications will be available to add many different functionalities to your phone once you are comfortable enough with it.
