Blake,
Thanks for checking. This was working great before update. I have three days to decide whether to keep. It's extremely frustrating.
Unless you return it for an older phone that's not likely to see any major OS updates in the future, having Flash again will probably be fairly short-lived. Adobe has already dropped pretty much all support for it on Android, and has said they'll be pulling it from the Play store in August I believe. While I agree that it sucks not having it fully functioning with the ICS update, it's regrettably something that we'll all have to get used to going forward on Android.
