While everyone focuses in on the Lumia 1020, 925 and 928 these days, T-Mobile once had an interesting Windows Phone 8 device dubbed the Lumia 810. Exclusive to the T-Mobile, the phone was an off-shoot of the Lumia 820 but it was more blocky and it only came in black. The phone never received much support, evidently not selling well, and it was recently discontinued, leaving many current owners wondering about future updates.

Indeed, the Lumia 810 is missing things like Wi-Fi calling and with it being EOL (end of life), there was no word if it would see the combo GDR2 and Amber update.

What we can tell you is that the T-Mobile is testing GDR2 right now on the Lumia 810 (see image below). What we can’t say is if this update is definitely coming. That’s because there’s a difference between testing a software update for a phone and actually signing off on it for distribution.
