Newest reply from Tmobile - its almost comical now. I just post a update every couple of days just to see what PR canned response I am going to get back. I may start making meme's at the 31 day mark.
Me:
# of days behind ATT pushing Lumia Black update for 925 - 16 days and counting. ATT also managed to push the update for both the 920/820 today. Maybe we'll see it before MWC2014.
TMobile:
