The trouble it takes to deregister this worthless iPhone 5 is incredible. The phone just stopped working and will not charge or come on. All I want is to deregister the phone number but miraculously you cannot do that if the phone is not capable of receiving the ridiculous confirmation code. The support page even asks if you have your phone or not. When you say you DONT have the iPhone, it wants to send a code to the phone you don't have so you can deregister it. Now that makes a ton of sense doesn't it? Please fix the worthless tethering you have done with imessage and disabling phone numbers when they switch to functional devices. This is easily the biggest reason I do not and WILL NOT ever own or use an apple device. I tried to talk my son out of it, but he had to learn on his own. I just spend 45 minutes online with a very nice rep, but a very worthless rep because as he was talking to me, I was 2 steps ahead of him on the support page and reading the worthless instructions when you DO NOT HAVE YOUR PHONE!!!!!!!!!!!!!!! Just deregister my son's phone number without attempting to send a code to a nonfunctioning phone. Then the rep accidentally hung up on me and never once asked for a call back #. My call back number is 806 778 7269 if anyone from tech support ever reads these. I doubt I ever hear back from anyone and I will never be back on this site except to delete everything with my name on it.
