Apple has put out a press release saying iOS 4.2 (technically iOS 4.2.1 I imagine) is available today for iPhone, iPod touch, and iPad. It's not showing up in iTunes for me yet (I'm getting an error saying nothing is available) but it should hit sometime in the very, very near future. (They say "today", not "right now"...)

“iOS 4.2 makes the iPad a completely new product, just in time for the holiday season,” said Steve Jobs, Apple’s CEO. “Once again, the iPad with iOS 4.2 will define the target that other tablets will aspire to, but very few, if any, will ever be able to hit.”

If any of you see it go live, let us know in the comments!
