You said you have an older iPhone too sometime in private. why not using this? Like, jailbreaking is against apples policys, and if something happens, the warranty is over instandly, but when you use an old phone it 1. might work better because there are more jailbreaks for older IOS versions and 2. you don't need it anymore so who cares if something breaks. I mean I am not sure if there is even something for IOS 16 or 15.
