When are the America's Got Talent 2012 auditions gonna be?

I wanted to go and audition for America's Got Talent for the 2012 series. But I wanted to know when AND where they were going to be. First tell me where to get the "wristband" because I heard you had to have that for the audition. Second, tell me where they have the auditions. I need it to be a state near Pennsylvania or even in Pennsylvania. So New Jersey, New York, places near Pennsylvania would work. And third, tell me the dates that there will be the wristband collection and the auditions. All information I asked for and further information (if available) would be greatly appreciated. Thank You.
