Previous statements such as this one saying the Lumia 810 will not be made compatible with the LTE network, despite being hardware compatible already, really makes me doubt whether moving to T-Mobile was a wise choice. And it raises questions about the coming major update to Windows Phone 8.1 (which appears to bring quite a few nice features such as notification center, week view in the calendar, etc.). Perhaps we won't see this update either? And, of course, since I made the move to T-MO in January I'm locked into a two-year contract.
So the question is whether there's a chance that we will see any of these updates. Does anybody know, or at least have educated guesses?
