The Evolution of iPhone: From the First Model to the Present


The iPhone, produced by Apple Inc., is a line of smartphones that run on Apple’s iOS operating system. It was introduced by Steve Jobs on January 9, 2007 and has seen regular updates and new models ever since. More than 2.2 billion iPhones were sold in November 2018 and it has a 15.6% share of the global smartphone market in 2022.

The iPhone was groundbreaking as the first mobile phone to incorporate multi-touch technology. Throughout its evolution, it has seen advancements such as larger screens, video recording, waterproofing, and accessibility features. Earlier models featured a single face button with Touch ID, while recent models adopted a bezel-less design with Face ID and gesture-based app switching. The budget series of iPhone SE still uses Touch ID.

The iPhone is one of the world’s dominant smartphone platforms and competes with Android. It occupies an important position in the luxury market and has contributed enormously to Apple’s profitability, making it one of the most valuable publicly traded companies. The impact of the iPhone on the industry is widely recognized and is credited with popularizing smartphones and the app economy. As of January 2017, the Apple App Store offered more than 2.2 million apps for the iPhone.

Production :

Until the iPhone 4, all Apple devices were made by Foxconn in Taiwan. In 2011, CEO Tim Cook diversified Apple’s suppliers. The iPhone 4s was the first model produced by both Foxconn and Pegatron, and Pegatron’s share increased over time. In 2019, Apple investigated reports that some Foxconn managers were using rejected parts. In India, Wistron assembles iPhones for the local market. In response to China’s “zero COVID” policy, Apple announced that a portion of the iPhone 14 would be manufactured in Tamil Nadu, India, with the goal of shifting 25% of iPhone production to India by 2025. This strategy helps to mitigate supply chain disruptions caused by the pandemic.

iPhone Hardware & Software :

Apple outsources hardware production to external OEM companies while maintaining control over the end product. The iPhone encompasses typical smartphone hardware components, with some unique features like 3D Touch and the Taptic Engine. The touchscreen is the primary hardware, available in sizes of 4.7 inches and larger. Every iPhone includes a rear-facing camera, while the front-facing camera was introduced in the iPhone 4. The iPhone 7 Plus introduced multiple lenses for the rear-facing camera. Various sensors are present, such as proximity, ambient light, accelerometer, gyroscope, magnetometer, facial recognition or fingerprint (depending on the model), and barometer. In 2022, Apple integrated satellite communications into the iPhone with the launch of the iPhone 14 and iPhone 14 Pro.

Software :

The iPhone operates on the iOS operating system, which is based on macOS’s Darwin. It utilizes Cocoa Touch and UIKit instead of AppKit and Cocoa for its user interface. The graphics stack runs on Metal, Apple’s graphics API. The device comes preloaded with Apple’s built-in applications and supports the download of third-party apps from the App Store.

Apple offers free over-the-air updates for iOS, accessible through Finder, iTunes, or directly on the device. Major iOS updates usually coincide with the release of new iPhone models.

The App Store was introduced with the launch of iPhone OS 2.0 in July 2008. Initially, third-party web applications were supported, but later Apple released the iPhone SDK in 2008, enabling developers to create native apps. All third-party apps must be downloaded from the App Store, except for enterprise ad-hoc apps. Developers are required to enroll in Apple’s Developer Program, which involves a yearly fee and grants access to various resources.

Apps on the App Store go through Apple’s app review process before being available for download. Apple reserves the right to reject or remove apps that are deemed inappropriate. The company’s strict control over the App Store has garnered criticism from developers. Jailbreaking, which allows the installation of unauthorized apps, is not supported by Apple and may compromise device security.

The App Store has a vast collection of apps, with over 2.2 million available as of January 2017. Despite iOS having a smaller market share than Android, its app ecosystem is considered superior due to higher app quality and more exclusive releases. Apple’s review process and curated approach contribute to maintaining a certain level of app quality and security.
