Got the update in NYC. My data is still migrating, but I am intrigued. HTC and T Mobile have been pushing out updates to the phone very nicely, ahead of my wife's 810 in the case of portico and quickly in the case of HTC specific updates, which is a huge difference from my experience with an HTC android device on T mobile where I was stuck in antiquated OS **** forever.
I know the phone is LTE capable after checking the serial number, so I am hoping they enable that at some point. However, given T Mobile's late arrival to the LTE party, if this was enabling the LTE I think they would have put out some press release so I would bet against it. I would be very happy to be wrong.
