I did end up getting mine the other day. I did a factory reset as usual just to clear out any bug's and it seems to be running a lot smother then what it was. I def. like the new icons since they are the android version of the 3g and LTE.
I have the same thing showing up as well up in Greene County. Never noticed it till I happen to see yours and checked mine. Always had the BSL on to see where the towers where btw.
