In a recent podcast appearance, former Apple engineer Justin Santamaria recalled the first-ever FaceTime demo before the official announcement, including Steve Jobs' priceless reaction. FaceTime was introduced in 2010 alongside the completely redesigned iPhone 4 and changed the way people could connect and communicate with one another. The iPhone 4 brought a slew of massive upgrades over the previous generation and was the first iPhone to be shipped with an Apple-designed processor. The A4 chip made the smartphone snappier than the first two versions. It came with additional sensors to improve the user experience, like the gyroscope, which is a staple of modern smartphones and wearables. Arguably the most crucial addition came with software and the FaceTime announcement.
