IPhone 4

Apple iPhone 4 is the fourth generation of Apple's mobile phone. For the first time, for 4 years, the California 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 10 times faster than the previous model, in the amount of 600 thousand copies, which all disputes about the unsuccessful design were dispelled.

IPhone 4 was introduced as the "biggest leap" since 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 features that could not be covered in one presentation.
