On the LTE Hacks Facebook group, one of the mods says that the released version of the EP06-A does not in fact do Band 41, despite the fact that all the documentation says it does. I'm tempted to try it anyway since I don't have B41 on any towers nearby and probably don't have good enough LOS to pick it up even if they put it up. I have two B25 carriers and one B26 carrier, all of which are only 5x5, so if I could get any carrier aggregation going with those it would be great.
