Well, for the past month I have exchanged emails with ZTE & Boost/Sprint. Neither of them know nothing of an update that was promised. I really hope this is a mistake because that was one of several selling points for buying the boost Max. All over the internet forums, the reviews for the max/n9520 boost mobile & ZTE promised the kitkat update. Lynn La. A blog writer and she does reviews for Cnet was one of many. I emailed her today to see if she could get a confirmation. Will update when I do. Put pressure on boost mobile guys so we can get this. Just email them.
