Same here, still using the last "unofficial" app. It works great and see no reason to mess with it.
I saved a backup of the "unofficial" app just in case, but the reason I updated to the "official" one is to get Market updates when they come available (like when the eventually allow management of the DVD queue from within the app).
The "official" app works on Froyo too, despite the description saying only 2.3 devices.
