The Evolution Of The iPhone

It may come as a surprise to many people to learn that the iPhone is now in its fourth generation. This must have gadget was ground-breaking in its technology and design when it first appeared in the marketplace in 2007. Since that first iPhone was released technology has advanced rapidly, and the iPhone has been updated to the fourth generation which is available now. For the purposes of comparison it will be interesting to note the exact changes which have been made to the iPhone over the years.


When the original iPhone was released in 2007 it was hailed as an exciting new piece of technology. It had a lot of clever features, was stylishly designed, and was light and thin. Sales were respectable, but would never reach the heights of later models. The phone itself had 128MB of memory with a 620MHz processor. It was available with either 4GB, 8GB, or 16GB of storage. It had a 480x320 pixel resolution on a 3.5 inch screen. It also had a built in 2 megapixel camera. In short, for its time it was technologically a very impressive phone.

The next generation of iPhone, the 3G, was released only one year later in 2008. The design was exactly the same, and in general there were not many differences between the two models. The screen and its resolution was exactly the same, as was the camera, the processor, and the memory. One difference between the two was that Apple discontinued the 4GB version for the later model. This model also introduced sensors to the phone, such as the proximity sensor and the ambient light sensor. The main advancement, however, was in the connectivity. The iPhone 3G provided users with faster internet connectivity on the 3G data network, which heralded the beginnings of the iPhone as a multimedia device. It also allowed the iPhone 3G to be used, to a certain extent, as a GPS device.

Again, one year later, Apple had upgraded the iPhone again to the 3GS model. This was the point at which sales really began to take off on a global scale, and downloads in the App Store reached a staggering one billion. The iPhone 3GS saw a large leap forward in terms of the technology that was included in the phone. TheĀ  memory was doubled to 256MB and the processor upgraded to 833MHz. The phone had become much more powerful, making for a more enjoyable experience for users. The camera was also much improved, and was now 3.2 megapixels with the ability to record video. The battery life had also been increased, and there was a 32GB version available alongside the standard 8GB and 16GB versions. The phone also now included a digital compass.

It had now become customary for Apple to release a new iPhone in June each year, and they continued that tradition in 2010 when they released the eagerly awaited iPhone 4. Once again they succeeded in making the new version vastly superior to the previous model. The memory was doubled again to 512GB, and the processor upgraded to 1GHz. The resolution of the 3.5 inch screen was increased to 960x640 pixels to display crystal clear images. The camera in the iPhone 4 is 5 megapixels, and has the capability to record video in high definition. There is also a separate front facing camera with 1.3 megapixels and VGA quality video. The iPhone 4 is only available in 16GB or 32GB versions. It includes a three axis gyroscope, which holds great potential for increased levels of interaction with downloadable apps, for example with the rendering of maps.

It can be seen, therefore, that the iPhone has changed considerably since its inception in 2007. It is now faster and more powerful than ever before, and comes loaded with more features. What is unlikely to change much, due to its massive popularity, is the look and design. In terms of functionality, however, as technology advances users will be eager to see what the future holds for the iPhone.
