Finally got something I've wanted for awhile... An iPhone NAND programmer! This will allow me to remove iCloud lock from WiFi-only iDevices, and upgrade the storage on them! Can't wait to receive it! https://www.ebay.com/itm/152877203275 …
It is, but it's associated to the device by serial number. If you change the serial number in the NAND (on a WiFi only device), it de-associates it from that iCloud account.
