I "upgraded" to JB on Friday and thought all was fine until my alarm went off this morning. I always had the "use increasing volume" option checked off so that the alarm would wake me up gently. This morning I was rudely awakened by the alarm instantly chirping at full volume. PMO!!!! Not a good way to start the week. I checked the alarm settings, and it looks like JB got rid of the increasing volume option. Seems like a small loss, but it's an important one to me. Had I known about this in advance, I would have kept ICS.
