I bought the iphone 12;from my ex employer. The phone is factory reset but the remote agent still comes up on setup. I called my previous employer And they were no help. I know there is a way to remove the remote management with the Anyunlock program or other ones but once thats completed will the phone still show in the companies mobile client. And if it does show up will it show as inactive? Or is their any back door to take it out the MDM?
