In addition to new iPhones, Apple is launching a brand new version of its mobile operating system this month.

The new version is called iOS 7, and it will be available for iPhones and iPads. If you already have an iPhone or iPad, you’ll be able to download and install iOS 7 for free.

So what’s new?
