I bought the 6P with the intention of someday possibly moving to Fi. Now on Verizon, enrolled on beta sometime in mid Nov. Received the Nov update end of Nov. I just received the Dec update today. I believe this is the final beta build of 7.1.1. The next update should be the real deal. When? have no idea,.Verizon is always the last, usually after AT&T. I have had no major problems, just minor issues. I am a very light user & what is a minor issue to me could be a big problem for a power user.
