Joe is frustrated with replacement iPhones because they keep failing with the dreaded touch screen disease. So he bought a brand new one for navigating his DJI drone. How does it restore the old apps? Leo says it doesn't. It always goes out and gets the newer version. If he prefers the older version, he may be out of luck. But he doesn't want a SIM card for it. Leo says to use his own SIM card to activate the phone. Then pop it back out and it should stay activated.
