Well, the big problem right now is the backhaul. Lots of sites in Phoenix have been upgraded but because Cox and Centurylink won't get off their lazy backsides there is no fiber optic cable to hook things up to.I don't think are strong enough on executing to turn it around. Their magical "Vision" turned out to be snake oil and being bought out and fighting the Dish Network deal doesn't seem like good judgement. Their executive staff is clearly just looking to cash out.
They are working slowly it seems. Still, since my mid-August post we have had about 5 new LTE sites go live. Sensorly finally shows purple for Phoenix.
