Yes, I noticed the issue. It's pretty annoying.
I contacted the MIUI dev's asking about the possibility of an official release now that we've received an official ICS release from Samsung. Unfortunately, they most likely wont, at least not anytime soon. They are doing a poll on Facebook and they will work on official v4 releases for the top few phones. The skyrocket only has about 3 or 4 votes, where as the top 10 or so devices have several hundred votes. In fact the top 3 or so have over 1000. Such a bummer :/
