If you want to find out where someone is on their iPhone, there are a few different ways to do it. One way is to open the Maps app and type in the person’s name or address. If they have geotagged their photos, Maps will show you where they were when the photo was taken. You can also use the “Find My Friends” app to track down a lost phone or person. Just open the app and enter in the person’s name or phone number. The app will then start tracking it down and send you notifications if it finds it. ..
