I was just gearing up to initiate arbitration myself, after making about a dozen support contacts between both Microsoft and AT&T to reach a "final straw, no valid solutions offered" state.
well, technically, since it was pulled and you have to resort to black magic to get it working, you "technically" can still go that route
Well as more improvements are noticed, I also noticed a slight, insignificant, bug.
The positives? Bluetooth works MUCH better in my car. Cortana understood EVERYTHING i said. Previously, i had to connect to my 2.4Ghx network to get decent miracast to microsoft's screen sharing hockey puck, but with noticeable delay and pixellation. That is no longer an issue. I was even able to stream Netflix to my TV using miracast with no issue (besides the low quality streams Netflix uses for mobile)
The 1, tiny, insignificant bug? In the store app, sometimes an app will get stuck as pending (common issue) but it's still downloads and installs! for an app with stick at pending sometimes, then disappear from the downloading list. Like I said, an insignificant bug.
In ALL honesty, this should have been pushed out months ago.
Now things I still need to try.... treasure tag stability, since I keep one on my DLSR when I go to conventions, and overall stability testing.
