When Did the iPhone 4 Come Out

In the ever-evolving world of smartphones, few models have made as significant an impact as the Apple iPhone 4. As we journey back to the origins of this influential device, we will unpack its innovative features and recall its release date, which marked a defining moment in the history of mobile technology.

The Launch of the iPhone 4

The iPhone 4 was officially unveiled to the public on June 7, 2010, during the Apple Worldwide Developers Conference (WWDC) held in San Francisco. The device was subsequently released and became available for purchase later that month on June 24, 2010, in the United States, United Kingdom, France, Germany, and Japan.

This launch came almost three years after the original iPhone introduction, which revolutionized the smartphone industry, and one year after the release of the iPhone 3GS. With the introduction of the iPhone 4, Apple sought to push the boundaries of smartphone technology even further.

Key Features and Innovations

The iPhone 4 was not just an incremental upgrade over its predecessor. Instead, it brought several significant advancements and new features that differentiated it from previous models and made it a revolutionary product.

  1. Design: The iPhone 4 debuted a new design featuring glass on both the front and the back of the device, held together by a stainless-steel band that also acted as the phone’s antenna. This marked a departure from the rounded plastic back found on previous iPhone models and contributed to the iPhone 4’s premium feel and aesthetic.
  2. Retina Display: One of the most significant advancements introduced with the iPhone 4 was the Retina Display. The screen had a resolution of 960 x 640 pixels, which was four times more than the iPhone 3GS, and it boasted an impressive pixel density of 326 pixels per inch (PPI). This high-resolution screen offered sharp, crisp visuals that greatly improved the overall user experience.
  3. Front-Facing Camera and FaceTime: The iPhone 4 was the first iPhone to include a front-facing camera, which enabled video calling. Alongside this new hardware, Apple introduced FaceTime, a video-calling feature that has since become a staple of Apple devices.
  4. Improved Processing Power: The iPhone 4 also introduced the Apple A4 system-on-chip, providing improved performance and power efficiency compared to the processors used in previous models.
  5. iOS 4: Along with the iPhone 4, Apple unveiled iOS 4. This new operating system version introduced features like multitasking, folders to organize apps, and an improved Mail app.

The Legacy of the iPhone 4

The iPhone 4 was met with critical acclaim upon its release, with praise directed towards its design, performance, and the introduction of the Retina Display. The device quickly gained popularity, proving to be a commercial success for Apple.

In many ways, the iPhone 4 set the stage for future smartphone design. The focus on high-resolution displays, the addition of front-facing cameras, and the move towards a more premium look and feel have all become standard in the smartphone industry.


The release of the iPhone 4 on June 24, 2010, was a landmark event in the history of smartphones. The innovative features and design changes introduced with the iPhone 4 had a significant impact, not only shaping the direction of future iPhone models but also influencing the wider smartphone market. Even more than a decade later, the iPhone 4’s legacy continues to be felt in the smartphones we use today.
