Instagram
You can technically install
Instagram on an
iphone 3G, but the app may not function properly due to hardware and software limitations.
Instagram requires
iOS 10 or later, while the
iphone 3G can only run up to
iOS 4.2.1. Therefore, it's unlikely that you will be able to use
Instagram effectively on an
iphone 3G. It is recommended to use a more modern device for the best experience.
