but sprint is now part of tmobile. so it should come soon. I don't see why the unlocked need to wait. they test the carrier versions because the carriers add stuff that may or may not work. unlocked is what Samsung intended it do and should already be compatible. so technically it should be first. doesnt make sense and no will explain the reason why.
as you can see I don't know heads from tales just trying to learn from anyone and everyone help at 61 I'm not as sharp with this technology and techniques again so sorry rkj az
