Ok, found it:
Recieved shipping label in Email on 10/4/08(day it broke)
Shipped on Monday 10/6/08 to Kentucky facility
Recieved item on Wednesday 10/15/08
So, 7 business days total, 11 days after it broke, before it was signed for on my front poarch.
I live in Mississippi, shipping address was in Kentucky.
I was just guestimating, this I'm going by from my email.
That email accompanied the shipping label email(which I can also copy/paste), that I recieved after the support call.
I can prove that I recieved my 360 back by 10/15, because the first thing I did was log on to XBL. I haven't logged on much since, so the latest it would show me logged on is a few days ago, at least.
My gamertag is Zenfoldor.
Today is the 19th. The longest it could possibly have took(If I'm lying) is 10 business days(or 9, because I think Columbus day happened in that time frame).
So, any more questions regaurding my anecdotal, true, and provable experience exchanging my 360 in a timely manner can be supplied with more evidence, following more investigation.
I have changed the email photo in order to not show vital information(I hope).
