Well, we have the Amber update rolling out to everyone. We also know that Windows Phone 8 supports WiFi calling, since the 925 and 520 both have it. Now, I can live without the FM radio, but the lack of WiFi calling is a problem. I work in a building that cannot get T-Mobile signal at all. I do, however, have good WiFi signal.
Are there any plans out there to bring WiFi calling to the 810?
