Couple of items.
Have used the 'test' Wimax tower in Springfield (now Clearwire tower) for nearly 3 years. It is no longer in service, had to switch to big red for MiFi - bummer (only for work 8-5).
Also, have talked with local store Sprint reps several times this year.
LTE was first due before summer, then by July, now end of summer (end of September ???).
According to reps this is due to Comcast not hooking up fiber for towers (at least in a timely fashion).
Am trying to hold off moving to big red for phone service so I can have decent evening data speeds, but not sure how long I can endure at .04 mb speeds.
Anyone out ther have a different or more recent update - my last info above is from the end of June.
