Find My iPhone
I recently lost my iPhone 6, however, I had the find my iPhone application installed and registered. When I tried to find my phone, though, it wouldn't work as the phone was either off/dead/etc and labeled "offline". I then reactivated an old iPhone using the same iCloud username as the lost iPhone 6. When I use find my iPhone now, it shows both devices, my iPhone6 and the reactivated iPhone 5. Since I reactivated the iPhone 5 with the same iCloud username, is it doing me any good to keep watching to see if the iPhone6 that's still on find my iPhone comes back online? I figured that if the iPhone 6 was turned back on, it would still register with my iCloud info as long as it wasn't wiped. Is this true or should I just use the "erase iPhone" feature of find my iPhone to wipe that one clean?
iPhone 6, iOS 9.0.1
