Update: We're getting reports that this should be rolling out in full-force now. Anyone get theirs today?
Update 2: We're hearing that a lot of people are still without the update, so we pinged HTC to make sure everything is rolling as planned. Everything is right on schedule, so just sit tight -- it should be hitting your device anytime now.
Update 3: After months of silence, it seems the beast has awoken, and the update is rolling out yet again, with the same version number 4.06.605.3.
