    Hi guys,

    Loving the 521 by the way, it was an impulse buy at $35 but after using it for a month I have to say it was probably one of the best tech purchases I've made.

    So my question is, by installing WP8.1 through the developers program do I risk breaking the wifi calling function through T-mobile? I find myself using it quite a bit when working out of the U.S. If so I may have to impatiently wait for the update to come through T-mobile's pipeline sometime this summer.

    Yes you may risk the WiFi calling feature breaking I would suggest that someone from T-mobile who is going to install WP8.1 onto there device to try it out and see if it does or not break the feature.

    Or get a cheap WP8 device and try it out for your self if you want.

    I also assume an update would mess up WiFi Calling. I have an HTC 8X and accidentally got WiFi Calling last year but the next update took it away. I'm pretty sure T-Mobile has to integrate the WiFi Calling software with the OS.

    Yes it will. WiFi calling will break with 8.1 preview.

    Hmm...I'm getting conflicting info, lol. I guess I'll just have to try it out myself to find out!

    YMMV, but realize that once you come on, it is not easy to roll back.

    This indeed is a case by case basis. Some people report it works, while for me and others it does not.

    If it is enabled, I cannot even send text messages. So for now, it is disabled. I'm not usually on WiFi long enough to merit using it anyway, so not a big loss for me.

    Yeah I can't send texts either from my 521 when its enabled.

    Texts over Wi-Fi work but sending a photo along will not.
