IPhone 4

iPhone 4 is the 4th generation of iPhone, and this is the first iPhone to receive a major design refresh since the release of the iPhone 2G. This introduced a stainless steal border and a front facing camera, as well as 80 new features that came with the software. This product was released on June 24, 2010 at $599, which is as expensive as the current iPhone XR.

This product was very expensive for its time, beating the iPhone 2G by $100 in the starting price. However, this product sold very well as all of the new features convinced a lot of consumers.

Features
1- FaceTime HD Camera

This iPhone launched with a second camera that was on the front. People could now take photos with the front-facing camera, and make FaceTime calls.

2- A Chip

This iPhone introduced its first processor chip created by Apple themselves, the A4 chip. This would make the iPhone faster. Previously, Apple used processors from Samsung, which were not very fast.

3- Better Display

The screen resolution nearly doubled from its predecessor, becoming the sharpest display in a smartphone in 2010.
