Thanks for your reply, and for being able to see through my typo. I hadn't considered the possibility that the major developers might not yet be up to speed with the release of this long-awaited OS/browser combination.
I wonder if this means the PC paradigm -- box, display, keyboard, mouse -- is rapidly being phased out by an . . . iPhone that Tweets when swiped?
For your insight you would get a little gold cup, but I am unable to locate its icon. Anyway, it's the thought that counts.
