If you still own an iPhone 4, chances are it's sitting in a drawer somewhere gathering dust. You've probably thought about throwing it out, but now there's finally something useful you can do with your old smartphone instead: turn it into a feature phone.
That's what one Reddit user did before sharing a picture of their simplified iPhone 4. After the photo shot up to the front page of Reddit, they offered a full step-by-step guide, which involves jailbreaking the phone, redesigning the home screen, and disabling a ton of software features.
It takes a little work to setup, but it's the perfect solution if you need a basic backup phone or you have a grandparent who's uncomfortable with technology but wants to stay in touch.
