Interesting that Jobs complained 'sub-standard apps', and then allows PhoneGap? I think PhoneGap is a great tool and should be allowed, but look at some apps made with it. They feel chintzy to me. Navigation bars and toolbars don't stay on screen when you scroll for instance.

I don't think that's really a big deal, but the logic doesn't work if that's your reason for 3.3.1 and blocking flash.
