Looking to take your iPhone back to the very first version of iOS? Well if you’re feeling a bit retro, here is a step-by-step break down for you of how to downgrade from iOS 3.1.3 Back to iOS 1.0. iOS 1 represents a look back in time to show how advanced the iPhone was back in 2007. Before the iPhone came out, smartphones were completely different. They all had very small screens and only a handful of them were touch screen. By looking back on iOS 1, you can see how much thought Apple put into creating the phone of the future. By downgrading, you get to relive some of that nostalgia. Keep in mind the App Store did not exist back then, so you will be limited to Apple’s built in apps.
Please Note: Downgrading is frowned upon by Apple and is only recommended for experienced users. This guide is for research purposes only and SonnyDickson is not responsible for any damages caused by this process. Proceed at your own risk.
