Are they? Or have they already stopped signing it. My battery life on my IP6 went down considerably, and considering I did not have any problems with 8.1.1, I wanted to go back. I'm not sure yet if I want to downgrade my Air 2 back to 8.1.1. yet, but I better make up my mind soon. On a side note, it's crazy that we have to scramble to do this still before they stop signing their firmwares. Why can't they just be decent and let you install whatever version you wish without hassle.
