why does windows say that the 925 Lumia has 8.1 but tmobile doesn't allow for the update. check there site it says 8.1 was released on at

check the windows. Site it says that windows 8.1 is available for the 925 Lumia on T-mobile and at&t. So why are we not getting it. You'd think that with the competition between T-mobile and at&t they'd jump on that. But what is going on between t-mobile and windows. NOT KEWL!!!!
