With all the R U M O R S and BS flying around the net and the supposed firmware needing 2 weeks to go through the carrier, I am leaning on the 20th, if I am wrong I am wrong but from all the reading on here and other places and talking to AT&T corporate people, Monday is not looking good.
Even if it is Monday I will not be the one in line, than again I honestly do not think there will be any lines, NO reason for it and you still have people on here trying to sell there older models of the iPhone for ridiculous prices , allot of people are going to be S T U C K with old equipment.
