OpenAI’s ChatGPT is now more accessible than ever, having expanded to virtually all platforms, from desktops to mobile devices. It’s a testament to the company’s wide-reaching capabilities, offering AI experiences on nearly any internet-enabled device. However, when it comes to iPhone compatibility, ChatGPT officially supports only the latest models running iOS 17 or newer. Yet, a spirited 17-year-old developer has defied these limits by successfully running ChatGPT on the venerable iPhone 3GS, with fascinating results.
The innovative solution comes in the form of an app called “ChatGPT for Legacy iOS.” This app acts as a client that bridges the gap for older devices unable to run OpenAI’s official version. Despite the difference in platform, it delivers nearly all the same functions as the modern app, courtesy of the official OpenAI API. The developer assures users that this application exceeds being a mere “proof of concept,” providing features like contextual memory, chat history, and even visual search via uploaded images, lifting aging devices from obsolescence.
“ChatGPT for Legacy iOS” is designed for older iOS versions, transforming how these devices interact with the OpenAI API. Users can engage in detailed text conversations, analyze images with ChatGPT, and generate visuals—all familiar capabilities from contemporary chatbots. Conversations are conveniently saved, allowing users to revisit them as needed.
For those possessing an older iPhone, compatibility requires iOS 6 or later, meaning the app will run on an iPhone 3GS or newer models. However, there’s a small hiccup: the app isn’t available on the App Store due to distribution limitations. Therefore, installing “ChatGPT for Legacy iOS” requires jailbreaking the device.
After installation, a ChatGPT API key, obtainable from OpenAI’s website, is needed to activate the app. Detailed instructions and the source code are available on GitHub for those interested in undertaking the installation process and reviving their old iPhones with this groundbreaking app.
