I can't quite remember, but I think it is Google Services Framework in Application Manager where you can go in and clear the data and cache and possibly to get the update (that is if it has been release) to possibly fake the que out and get the update forced to you early. I think that is how I got my 4.1.2 earlier.
Anyone try that? But like I said, that is if it is even released and up on Sprint's servers yet. I was a happy camper simply waiting on an unknown date, but when someone posted the 11-06-13, it got me excited - Dang! :-(
