Really? That's much earlier than I expected. Can anyone else confirm getting the update? Nokia technical support believed that if T-Mobile finally rolled out 8.1 on their own, I might regain the Internet Sharing I lost back when updating to 8.1, so I'm very curious.
I finally got the official download of Cyan from T-Mobile this afternoon approx 5 PM local time. It has successfully downloaded and installed. For my quick check of things that didn't work even with the latest Dev Preview.
1. YES WIFI calling works and,
2. MMS will work correctly even when it is on. Cool!
Good that it finally rolled out. I had flashed my phone to the Latin America ROM and currently running an unbranded T-Mobile 925. I'll probably wait till the update shows up on NSU, then flash. Unfortunately this update still doesn't unlock the APN settings so I won't be able to use the foreign SIM trick to get Internet Sharing on Cricket
