Nice follow-up on that situation.

I do not have a PW-2 in my collection of Kindles to play with myself.
But it does have a long history, it was the first i.MX6 based device produced, nearly a year before the other '7th gen' devices.

So unless we get or hear of a lot of complaints about 'feature changes' in 5.7.3, then all we can do is pass along the story of this one person's experience (that 5.7.3 fixes the problems with 5.7.2).

There have been questions scattered around the forum of what version we recommend (5.6.5, 5.7.2.x or 5.7.3.y) -
So for the PW-2, I guess all we can do is point at this story.

There is a more general, "hot issue" for our technical research to spend time with now -
The removal of our "developer keys" by simply making contact with the Amazon servers (just as if a person changed their registration status).

That one will become a real PITA for our users if Amazon deploys it across their system.
(We think it has only been in 'trials' so far on a few of their servers, either by accident or as tests.)
And it effects **ALL** Kindle models, at least back to the K2.
This one is not a rumor - my K2 was effected while I had it in my hands, watching it.
Other people, other models, reported the same thing during the afternoon of April, 4th.

It was just a stroke of luck that we happened to have a 'tool' on hand to recover the 7th gen. devices from that situation.
