Update, 7-25-14: It looks like this over-the-air update was delayed for some reason. Samsung says it's coming in now.
KitKat is making its way to the Galaxy Note II. We've seen it come to Sprint, and just yesterday it started rolling out to Verizon's version of the handset. Now US Cellular has updated the support page for its Note II to say that KitKat is on its way.
