Weird...ordered online through att and...

As of Monday, 9/28/15, I ordered the silver/white (whatever you call it) 128gb Iphone 6s plus. I just added a line through next and am going to pay off my other line, have a Note 5, great phone!! Just miss Apple, yes it just works!! Anyways, it said on att.com the typical 3 to 4 week window. I received no emails, nothing, they took the money out of checking for "next" and thought it would go back today, but got an email from UPS and sure enough it is arriving tomorrow! I am SHOCKED! I have a premium account through school, but last time I used it, I had to wait awhile for my phone, so I am not sure if I got lucky or what? Anyways just an FYI to those looking to get one now. Hopefully you will have the same luck as I did!
