A trip down memory lane: With OldOS, iOS 4 comes 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 everything was better back then or who wants to take a little time travel back in time, there is now good news.

Has in loving detail Zane, an 18-year-old New Yorker who is still in high school, has developed an iOS app that brings the iOS 4 feel 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, but they are being worked on, as Zane explains.

Today is Launch Day 🚀

Introducing OldOS – iOS 4 beautifully rebuilt in SwiftUI.

* Fully functional, perhaps even usable as a second OS.

So if you’ve 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 Apple’s test flight download.

But be warned: In the past, Apple collected such apps relatively quickly for violating the App Store Terms of Use – so anyone who wants to test OldOS has to be quick.

The other possibility would be that you just build your own OldOS – Zane kindly has all the code on it GitHub divided.
