I've been modifying these 7921 phones by going to settings,
then unlocking network profiles with **# , however I think the latest 8.1 phone loads have changed something as EVERYTHING but Phones Settings is grey'd out and nothing happens when you try to unlock the settings with **#. When you go into Phone Settings everything is grey'd out as well.
Is there a new unlock sequence? I cannot locate any mention of this anywhere. Thanks!
