According to the rumor whose iPhone 5 would have a larger screen included a good part of the iPhone user community and a Italian site he thought of making some images comparing the dimensions of the current iPhone with those of one with a larger screen. The Italians present terminals with screens of 4.3, 4.5, 4.7 and 3.5 inches, but as far as I can see, they did not think to make a picture showing the most likely size of the screen, the 4 inch one. Returning to the comparison made by them, we notice what was probably already obvious to many, a larger screen would also represent the launch of a larger terminal.
Although the result of the comparison was obvious to everyone, there is still an interesting aspect: increasing the size of the screen and keeping the resolution would lead to a decrease in the number of pixels per inch, so we will no longer be able to talk about an iPhone with Retina Display. Apple is not ready to give up this name because iPhones with retina screens sell well, the term can be used in advertisements to attract customers and a screen with larger dimensions than the current ones would leave the iPhone without one of its strengths.
My opinion is that an iPhone with a 4-inch screen would represent a step forward for Apple because a 3.5-inch screen becomes much too cramped for applications and the world wide web.
