Windows 10 mobile for Lumia 640 (AT&T) firmware have been released finally.
The version 1511 build 10.0.10586.318 have been release to Lumia 640 (AT&T)
Since my phone running on Windows 10 Insider Preview Build 14352, I need to use Windows Device Recovery Tool to restore my phone back to Windows Phone 8.1
And then, install the apps "Upgrade Advisor".
Upgrade to Windows 10 for mobile, it will be 10.0.10586.107
Run the update again, it will upgrade to 10.0.10586.318
