1. Can't say when... After AT&T gives the approval.

2. I'm sort of vague on this. AT&T approves it. I think they just give Microsoft the OK to push it? Maybe AT&T pushes it. Same difference really. You can't get it until AT&T says you can. Unlocked SIM tray doesn't matter. Location doesn't matter either. The OTA will find you in Bangladesh.



If you use Insider on the Release Ring, the same version is fetched as the recent public Upgrade received by these phones (10.0.10586.xxx): Phones Eligible for Windows 10 Mobile Official.

If your phone is on the eligible list and you go Insider and stay on the Release ring you get the next public version early as Release ring in effect is the RTM. This will deliver the most stable Redstone builds to you earlier than OTA push with minimal risk.

For right now, Windows Device Recovery Tool is only flashing 8.1 to models that did not launch with 10 so it is the way to revert if you don't care for W10M: How can I recover/reset/restore my phone software?
