yes, i’ve heard the same info, but i would like official confirmation.
btw, to the best of my knowledge, band 5 is not actually used in the USA, except in one small part of one city that is 1800km away from me (namely, Miama, FL). bands 2 and 4 are the main ones. (band 4 is present on 10 III, but not band 2, and i get ok reception, but never good)
