When Steve Jobs rises from the grave or Apple products support Flash.

I would say when it officially is released (not preordered) but when its available to walk into an apple store and physically buy one. They are waiting for all the hype to go down and all the contracts to be signed until they roll out the unlocked ones. September 21st would be my best guess
