iPhone 2G: Apple's first smartphone in 2007

Apple's entry into the smartphone market occurred on June 29, 2007, with the launch of the brand's first advanced iPhone, the iPhone 2G. This phone received a modest response from the public, although it is not comparable with the recent successes achieved by the brand, nevertheless it sanctioned Apple's challenge to smartphones with Android operating system. The iPhone 2G had a memory of 8 to 16 GB, a 3.5-inch display with a resolution of 480×320 pixels, with overall dimensions of 115 mm high by 61 mm wide.

The weight of the iPhone 2G was quite low, about 13 grams, and was equipped with the innovative iOS 3.1.3 operating system. Surely this phone was already an advanced device, however the connection speed was quite limited, also due to the technologies of the time, which were still based on the 2G system. The design was sober and balanced, with some interesting applications, which made it competitive with Android smartphones from Samsung and other brands of these years.

iPhone 3G: new operating system for the model of 2008

The following year, in 2008, the new model of Apple's iPhone is marketed, the 3G, which comes with a completely revised design, while the technical features remain almost the same as the previous version. In fact, the iPhone 3G mounts a 3.5-inch screen with a resolution of 480×320 pixels, for a weight of 133 grams and dimensions of 115.5 mm high by 62.1 mm wide. At the same time, a new operating system, iOS 4.2.1, was introduced, which, together with 3G connectivity, allowed for much faster browsing.

The same year also saw the launch of the App Store, the digital platform from which Apple applications can be downloaded for the iPhone, iPad and all other mobile devices developed by the Cupertino company. This model is more successful among users, sanctioning the final entry of the brand in the smartphone industry, which had large profit margins and was already manifested as one of the most promising in the consumer electronics market.

iPhone 3GS: the evolution of the 3G model

In 2009, models are not released particularly innovative, in fact, Apple released the iPhone 3GS, which, however, has some important technical innovations.

In addition, the third model of Apple's iPhone boasts an advanced display of the latest generation, with a multi-screen system extremely sensitive and efficient.

The technical aspects are not dissimilar from the 2008 model, with a 3.5-inch screen, a weight of 135 grams, dimensions of 115.5 mm high by 62.1 mm wide, memory of 16 or 32 GB and resolution of 480×320 pixels.

iPhone 4: the history of the iPhone continues

The strengths of the iPhone 4S are the dual core processor A5, HD video recording at 1080 pixels and 30 fps as well as the two advanced cameras, the main one iSight 5-element 8 Mpx and the front camera 0.30 Mpx.
