How do I find a device ID from an erased iPhone?
I got a new iPhone 8, and I set it up to work perfectly with my existing carrier, Verizon.
Now I want to trade in my old Verizon iPhone 6. I've already turned off "Find my iPhone" and fully erased it. However, now Verizon wants my device ID. I can't figure out how to determine the device ID because it's erased and I can't get into the "About" screen anymore. Help?
Any of the following will work: serial number, IMEI, ICCID, WIFI address, or MEID.
iPhone 6, iOS 10.3.3
