last time i checked AT&T (and authorized retailers, where many of you are probably having problems) are capitalist businesses, with the right to refuse service to anyone, for any reason. sorry it makes you pissed off that you can't buy the hottest latest blackberry, but nowhere in any literature does it state that AT&T MUST sell you the device if it is in stock.
on a helpful note- upgrade to familytalk and add a line for 9.99/mo. not only will you get the phone for about the same price after the 2 years, but the sales reps will love you, as new apps are like heaven to us.
