I ordered way before you and got a date of 10/7...called VZW today to validate and they are standing by that date. Not sure why the rep told you to expect it tomorrow and then say between tomorrow and 10/14.
My location is N215401 and my order number is 835xx, I wonder if we are in the same location. 3:50 ET is when they said they received the order. I was so tired from staying up I wasn't sure exactly what time I sent it, but that sounds about right.
I think the rep was just throwing all kinds of info at me probably didn't want me to flip out or something, which I wouldn't have done. They have been standing by the 9/19 date for me for the last few days with the exception of one rep who said the 10/14, when I questioned a supervisor about the 10/14 date she said that was if I ordered the phone today and didn't do the early pre-order. lol I am switching from AT&T to Verizon and this doesn't give me the highest level of confidence about making that switch.
