Just had an update notification on my HOX saying that software update 4.0.475679 was available. Wondering why they were pushing out ICS updates with JB around the corner I installed the update and rebooted. When it was back up and running I did a check for new updates and lo and behold it said software update 3.14.161.27 was available which contains JB 4.1.1 and Sense 4+

It's downloading at the moment.......
