That's my concern, too. If I need to opt-out of the Preview or not, to get the Black update. Does the GDR3 Preview differs from the official release, or they are just the same? Also, are all devices going to be updated within this month? If so, I'm finding it a bit slow. More countries and devices should have gotten the update by now. Or, I guess I just need to exercise more patience. Lol!
Opting in opting out of the MICROSOFT'S ( that is the key) Preview for Developers has 0 effect on
whether or not you get or
don't get LUMIA BLACK. 0, nada, null, zero, zip.
Update 3 (GDR3) is the same as it appears in Lumia Black. If you read about Black in the first few days it said
China was first and in the
following weeks other countries would start to see a rollout, it didn't say EVERY
other country all at once would but said "start to roll out with the update." It's be 5 days ?
This happened with Amber why are so few remembering the time it took with Amber?
some still don't or didn't get Amber, you just have to wait. :wink:
