I received the update message this morning. The only news is it helps "random" resets, which I'm all for, so I figured, "Why not?"
So I tried the update, and of course I needed more free memory. So I used Elixir 2 (rave, rave, awesome app) to sort apps by code size and move the largest to SD.
I moved the clock forward a month, got the update message again, tried it again. Then had the problem where the update counts down to restart, but never does. Long story short, I moved the clock back, forward, forward, back, no dice, finally had to wipe the cache.

Next the update came down without changing clock, and installed successfully. But as with a previous update, all my SD apps were now empty icons. I rebooted once more for kicks, and the good news is they all filled in while I was writing this.
I am appreciative and certainly not amazed HTC and VZW continue to update the DInc. It was one of VZW's best selling Androids, and so had an early large foundation. From the forum posts, there's still plenty of DInc users so it likely still has a large pie piece of their market.
