In 2010 Apple was a big company, but nothing could be bought with an existing company. However, that year, it introduced some of the most important devices in its recent history, such as the iPad or i The iPhone 4, is Apple's first tool showing the Retina.
These two machines are included a very different type of iOS than we currently have. IOS 4 stores the first build with scheumorphist icons, that is, icons that were exactly the same as what they intended to represent. Plus the screen was only 3.5 inches, so the difference from the home screen of your iPhone is huge.

The most noticeable change in the naked eye is undoubtedly the extra space we found thanks to larger screens. On the iPhone 4 we had 4 x 4 character grid, regardless of booth, in the new iPhone we keep 4 columns of icons but extend 6 rows.

As for the icons, we can split them into three groups: those that basically store their formats, such as Phone, Messages or Calendar; those that maintain the core but with significant changes, such as the Settings, Notes or Storefront icon, and that they don't look like something like Music or a thumbnail image.
In addition to all this, some changes should be considered, for example on iOS 4 we had the traditional YouTube app and Google Maps, both disappear with the options you downloaded from the App Store. And there's still another big change, you're sure you have it on your home screen now popular apps like Instagram or Snapchat, apps that in 2010 did not exist or were currently unpopular.
