At the time, smartphones were not as prevalent as they are today, and the iPhone’s introduction marked a turning point in the history of technology and communication.

The device’s sleek design and intuitive interface set a new standard for what a smartphone could be, and it quickly established itself as one of the most popular and influential devices of all time.

The first iPhone featured a 3.5-inch display with a resolution of 320×480 pixels, and it was powered by a 412 MHz ARM 11 processor and 128 MB of RAM.

It also had a 2-megapixel camera and could store up to 4GB or 8GB of data.

The device ran on Apple’s new iOS operating system, which was designed specifically for the iPhone and offered a new level of user experience.

The device was met with huge hype and anticipation, and when it went on sale in the United States on June 29, 2007, thousands of customers lined up at Apple stores to be among the first to purchase one.

Its popularity was further cemented when Time magazine named the iPhone its invention of the year in November 2007.
