So dev preview for amber for black will be the same for 8.1? There won't be another one to preview and we just keep this one?
No, this does not involve the Amber/Black/etc updates from Nokia or carrier
This is only for the MS Windows Phone Update. So, Windows Phone 8.1 is an MS update only, not much to do if anything with nokia really.
Amber and Black were from Nokia,,, GDR2 was from MS that came along with Amber I believe,,, GDR3 was from MS that did come along side Black update
There is not an update from Nokia in the WP8.1 update that I am aware of. (like Amber or Black)
When you get the Preview,, it pretty much is what will be sent out to all carriers I believe. So, correct, unless there is some sort of last minute change
and the carrier releases that change, you would get the updated change, but I do not think you would get the update again from preview otherwise.
But I am not 100% certain on that.
Dev preview app, wp central say that it may void your warrenty. I contacted Nokia about it and they confirmed it. As much as I want to upgrade with dev preview, i wont. I cant risk it.
I did the GDR3 update through the Preview and had no issues. I will be doing the WP8.1 update as well.
I will be posting about it when that happens.
