Switching phones
I had switched to another IPhone earlier in the year. I kept my old phone if my current one broke. I was going to give my phone to a friend but I don’t know how to reset it back to the factory standard. I have already transferred my data to my current phone, I just dunno how to delete the data on my old phone safely, while keeping the data on my new phone.
Thank you
