The iPhone changed how people use mobile phones. It helped make the "slate" shape popular for all smartphones. It also created a huge market for smartphone apps. This is often called the "app economy." Today, there are nearly 2 million apps available in the App Store.

Using an iPhone involves several clever steps. First, you interact with the screen using multi-touch technology. This means the phone senses your fingers touching the glass.

To unlock the device, you might use a fingerprint sensor called Touch ID. Newer models use Face ID instead. This system uses facial recognition to identify you.

You can also navigate the phone using gestures instead of pressing a physical button. These steps happen very quickly to help you use your apps.

Apple began working on a smartphone in 2004. They started a secret project called "Project Purple." A team of 1,000 employees worked on this task. The team included hardware engineer Tony Fadell and designer Jony Ive.

Steve Jobs led the team and changed the focus to a phone. Apple worked with Cingular Wireless to build the device. This development cost about $150 million over thirty months. Steve Jobs finally announced the first iPhone on January 9, 2007. He presented it at the Macworld convention in San Francisco.

Many different iPhone models have been released since that first day. The original model had a 3.5-inch screen and launched in June 2007. The iPhone 3G arrived in 2008 and worked in many countries. Later, the iPhone 4 introduced a Retina display with high resolution.

The iPhone 5s was the first smartphone to use a 64-bit processor. More recently, the iPhone 17 series includes models like the Pro and the Air. As of July 2025, more than 3 billion iPhones have been sold worldwide. Apple has been the largest mobile phone vendor since 2023.

An iPhone is a lot like a tiny computer in your pocket. Just as a computer uses software to run games, the iPhone uses iOS. You can connect it to other tools like the Apple Watch. The phone also connects to the internet to find information. This is what the "i" in iPhone stands for. It can stand for internet, individual, instruct, inform, or inspire. These devices help people stay connected to the world every day.
