iPhone 4

Iphone 4



Apple iPhone 4 is the fourth generation of Apple's mobile phone. For the first time in 4 years, a Californian company decided to radically change the design, which caused a lot of controversy. Despite this, on the first day of pre-orders, it was sold out 10 times faster than the previous model, in the amount of 600 thousand copies, than all disputes about the unsuccessful design were dispelled.

The iPhone 4 was presented as the “biggest jump” since the release of the first iPhone, and experts have already suggested that this version of the iPhone will become the “gold standard” for all mobile devices. All this is due to the fact that the new model has more than 100 new functions that could not be covered in one presentation.

  • The size of the display remains the same, but the resolution is increased to 960 × 640 with a density of 326 pixels per inch, which is four times more pixels per inch than in the 3GS, which means that it is the best display used today in smart phones.
