OldOS shows you what your iPhone would look like with iOS 4

A Trip down Memory Lane: With OldOS comes iOS 4 back to your current iPhone, including working apps.

In November of this year it will be ten years since Apple launched iOS 4 – Back then, the iPhones 3G, 3GS and the iPhone 4 were the hottest shit. For everyone who thinks that everything was better back then, or who want to take a little trip back in time, there is now good news.

In loving detail work, Zane, an 18-year-old New Yorker, has still attended high school, developed an iOS app with which you can bring the iOS 4 feeling to your current smartphone. OldOS, as the developer called the app, should be as close to the original as possible. This also means that all of the native apps work and are fully usable. Only with Youtube and Messages there are still a few difficulties, which are being worked on, as Zane explains.

Today is Launch Day ????

Introducing OldOS – iOS 4 beautifully rebuilt in SwiftUI.

So if you have always wanted to see what websites from 2021 would look like in a ten-year-old version of Safari, or how photos or notes were organized in iOS 4, you should check out OldOS, which is officially still in beta is to download via Apple’s Testflight.

Be quick or do it yourself

But be warned: In the past, Apple has such apps because of violations of the App Store Terms of Use collected relatively quickly – if you want to test OldOS, you have to be quick.

The other possibility would be that you just build your own OldOS – Zane kindly shared the entire code on GitHub.
