An app called OldOS (via The Verge) recreates the iOS 4 experience on a new iPhone. An open source project created by 18-year old developer Zane, OldOS uses SwiftUI to create a near pixel-perfect iOS4 experience, down to such details as the unlock slider and original wallpapers. It also brings back the original look of many iOS apps, including Photos, Maps, Safari, and Notes.
Today is Launch Day 🚀
