I'm late to all of this going on but now am very much impacted by it.
The end of the BYOD phones.

I've contacted Sony to see if they will comment on the matter, but it is a shame this has happened at all in the first place.
I would recommend anyone to read James Parkers full article on the matter:
I apologize If this isn't the right place to post this.
