    I just received the update from T Mobile. Now my Wifi calling does not work. I am getting the error: ER02"DNS Error".

    I have the latest version of BBLINK. I did a full back up 2 days ago prior to the BB10 update. How can I fix this? This is the 1st problem I have had with my Q10.

    I simply forgot to reboot it.

    Have been searching for an answer and even gave Tmo's tech support a call. I'm usually based overseas where WFC has worked decently whenever there was a good connection. When I got to my cousin's place in Florida, WFC refused to work with his AT&T connection giving the ER-02 DNS Error. I visited a car dealership there and the same thing happened.

    After the session with TMo's support, I tried connecting to a Comcast connection and it worked perfectly...no need to reboot or anything. I was honestly really scared that TMo had pushed something to my phone/SIM to disable WFC and force me to downgrade, given their anti-Blackberry stance.

    Anyway, hope this helps someone.
