I registered for the technical preview, they updated my 8s to 8.1 and now I can't here people talk, apparently Microsoft, in their wisdom dropped the volume in 8.1 from 30 down to 10 and locked it. Now I can't roll back to 8 so they basically killed a perfectly good phone. The reason I wanted to update was so that I could get data sense and have apps all run from the SD card. If they decide that windows 10 won't run on our phone, I sincerely hope they fix the volume because if they don't, there will be a lot of very angry customers.:angry:
