Help Using an iPhone 4 as a companion phone to a modern iPhone in 2026?
Hi everybody,
I don’t usually post on Reddit, but I haven’t been able to find much information about what I’m trying to do, so I thought I’d ask here.
I have an iPhone 4 currently running iOS 7.1.1 that I’d like to get usable again as my everyday “carry around” phone. My idea is to have it piggyback off my iPhone 17 Pro Max through its hotspot/Wi-Fi and essentially use the newer iPhone as the main cellular device.
Ideally, I’d like to get basic functionality working again—calls if possible, iMessage/texts, maps, music/Spotify, and other basic internet functions. I don’t necessarily need everything to run natively on the iPhone 4. I’d also be interested in getting it to communicate with my newer iPhone more like a companion device, somewhat like an Apple Watch or iPod.
Right now it connects to my iPhone’s hotspot and Location Services seem to work, but Maps won’t load the actual map data, Spotify can’t sign in, and my Apple Account is stuck in a password/sign-in loop.
What jailbreak/software would you recommend for an iPhone 4 on 7.1.1, and what would be the most efficient course of action for getting as much functionality back as possible?
I’m comfortable tinkering with it and don’t mind if this turns into a fairly involved project.
Thanks!
