Whilst that's good news Josh mate, and helpfull 
It's not really something we should have to bugger about with. The polotics and back biting crApple get up to is... Disappointing. As we speak there's wranglings over google maps being dropped in favour of tomtom. You tube app dropped in favour of, well, nothing afaict. Why? licenses with google expired. Arrogance abounds.
No wonder there are so many Android owners.
It's upgrade time soon. Will have a look what's around then. 
Google Maps and gayTube definately dropped in iOS 6, more due to a spat with Google, rather than a tie-in with Tomtom (Google also own gayTube).
From a technical security perspective, I can see the reasoning for lack of Flash (and other similar frameworks), and not purely due to the poor state of Flash. It can break security of the device, which crApple will claim makes the device more vulnerable to attack (it does), and cynics will claim it reduces crApple's tight grasp of the platform (it does). But, either way, this should not become the user's problem.
TBH, I don't miss Flash on the phone. Never really noticed its not there. Adobe has pretty much said that Flash is to be abandonned. We can hope utube is abandonned with it, but I'm not that lucky.
For info, Windows 8 in its native mode will not support Flash either. Or Java. Or any other browser plugins. These technologies are not required with HTML5, and web designers will have to pull their finger out and drop all this old shite. But they won't. Until they *have* to.
Up until now, I can only think of one good website that implements Flash technology in a well thought out, integrated way. Thats Oracle's My Oracle Support site. The flash site is being decommisioned in 2 days in favour of an HTML format. Flash has no use in the modern world
