Verizon Wireless hasn't issued it yet. Soon probably though.
VZW will be the last US carrier to release KK 4.4.2 to its customers as usual. VZW is maybe still adding bloat and stripping the useful features we are looking forward to maybe. Just hope it will be a good release not a failed update.
T-Mobile can't compete for coverage so the have to compete with the phones they offer and the price of the service.
I would be safe to assume Verizon will release KitKat for the Note III 1 month after all other carriers get it.
I don't need the answers from VZW that don't mean anything to me. I have been around and know where to find answers to the my questions. These links you leave don't mean much to me and do more for you to end up with an upset customer. You did not say enough to make me want to leave VZW at this time but I am always looking for something better as my needs change.
