The iPhone 5
is the first iPhone with a screen larger than 3.5 inches. Because of this, both Apple and developers have had to tweak their software so that it takes advantage of the bigger display. But while it'll certainly take some time for developers to update all their apps, Apple has of course made sure to optimize its software. What changes has the new screen size caused? Well, it'd be a bit of an overstatement if we say that there's anything groundbreaking, but the phone has certainly become even more functional and easy to use because of this.
