We are live in New York City at the Mango Update event. We have a lot of features we've already seen or are expecting to be officially unveiled today - Multitasking, Twitter, Navigation, and more. With 500 features promised, though, there's sure to be some we haven't seen before. Catch us after the break for the full live blog - starting at 10 Eastern / 7 Pacific - and stay tuned for more updates later today!

Update: we've embedded the livestream after the break as well, so you can watch our pithy commentary and the event at the same time. As always, Dan's updates from the ground will tend to be just a little bit ahead of what's coming over the livestream.
