Well, I have finally gotten to experience b41 for the first time today. (Thanks to SpenceSouth) Its definitely widespread in Jacksonville. In my testing I averaged around 35-40Mbits per sec on the DL and about 11Mbit on the UL.
I'm using the Nexus 5 on older build modem so seems like my device only connects when in a b25 low signal area. Which for me is great b41 seems to fill in the holes pretty good.
With this three layered network Sprint is sure to win in coverage and speed. I went to some other forums earlier and all I saw was complaints. They must have never visited s4gru.
