I'm doing something particularly silly... I'm downloading it, but I'm too cautious to install it. Even though I really want it.
Oh, go with the serendipity brought him back part of the cat story. I figure, it's Apple software, it's publicly available on Apple's servers, it might inadvertently, or even by design, brick jailbroken/unlocked iPhones, but mine is neither. So it could freeze my iPhone to the point I have to do a full restore, but a full restore will do it. Besides, since it's 1,2 designated, not 1,1 as were the 2.0 betas and all previous iPhone firmware, it IS gold master, it IS what will ship on 3G iPhones, meaning it almost certainly will be the version released to the world. So, even if it's glitchy, they'll have to fix it, and the fixed version will trigger another update to the latest bug-fixed version. And even if it doesn't, if for some bizarre reason far behind the realm of acceptable version control, they don't increment versions between the buggy "pre-release" version and the fixed version, all you have to do is download the fixed version and do a manual install from iTunes and downloading iPhone firmware and doing a manual install from iTunes is Apple-supported procedure for people who can't get the auto-updater to work or need to update their iPhones offline.
Seriously, there are bound to be some bugs anyway, so you'll see a 2.1 or 2.01 firmware release, probably, anyway. Unless you like have clients calling all day, I'd go for it. I'm at home with regular phone to use, so I just can't wait kids.
Just need MobileMe to come back online. I wonder since they took down MobileMe temporarily if push mail will still work to my iPhone, even though the MobileMe web interface is down -- wonder if it requires I turn push on, or it's on by default.
