For this exact reason and never getting one single flagship Windows Phone(I do nit consider the 16gb Lumia 925 a true flagship) supported by T-Mobile along with not knowing what Microsoft is doing to change that alongside the constant bombardment of equally as good or better competing phones from rivaling OS's is why I am most likely leaving the Windows community at least for a little while. Also their constant efforts to supply the same rivaling OS's with features from Windows Phone means I won't miss a hitch. I plan to get the Sony Xperia Z3 and I can still stay in touch with the WPCentral app for Android, they now have the same Mobile Office suite of apps that we have, and they have a WP clock live wallpaper that features some of the same gorgeous typography and cleanness of Windows Phone along with their full app ecosystem. It's hard not to leave when you consider what's available. The Lumia 830 and 730 have not only been announced before the iPhone 6, 6 Plus, Sony Xperia Z3, and Galaxy Note 4 which all will be available before they are, but they have no mention of more than one carrier each and these are just midrange devices. How is Microsoft to entice consumers and developers with these kinds of practices? I thought this year would be the year that all changed but alas I had to buy my (soon to be up for sale)Lumia 1020 from eBay and get it unlocked for T-Mobile. The HTC One for Windows is the only known flagship coming to T-Mobile and ATT but nobody knows when. This is frustrating.
