On Xda there is a full system dump of 6.0 for the Tmo N5. A user had an IMEI problem odin back to stock fw and low and behold he had a system update to non other then 6.0. Now the waiting game for the devs to do something with that.
Let's see don't miss removable batteries never took mine out, SD card would slow the system down so don't miss that( Google it the information is out there) I guess I would like to see a 128gb option and red option with black Frame.
