No, Apple didn't state that in particular.
And read the wiki and this article:
HDMI - Wikipedia, the free encyclopedia AppleInsider | Apple brings HDMI output to iPhone 4, iPad, iPad 2
Actually it's no need iOS 4.3 only, the fact is the iPhone 4, iPod Touch, and original iPad can only output video at the max resolution of 720p. The iPad 2 allows for full, 1080p HD video mirroring.
So I suppose you should make sure choose the right presettings~
