Work Phone
Being that it is a "work" phone, can't the IT department use their MDM tools to issue an unlock?
I'm sure that they've already asked that, but I hope that they haven't just gone straight to Apple. Otherwise, this whole thing stinks of a false flag op.
The company I work for has the ability to reset the PIN using our current MDM solution so that all you have to do is swipe and set a new one.
