Sprint's "Up Its Sleeve" event is going down in New York City, and we're live blogging it for you.

We've known about Sprint's event for nearly a month now, but had no clue what it would be about.  Suspicions are running high that it is a dual-screen Android device called the Echo, but even that won't be sure until the event goes off.  Follow along with our live blog and see what this "industry first" is that the company has been talking about.
