Looking through this thread, I am surprised by the # of people who ordered through AT&T that have not received anything yet. Obviously, I didn't read ALL posts, but the general jist was that several of you haven't gotten your orders yet. I'm sorry, that really sucks.
I'm a long time lurker on here, first time posting, mainly this time because I also pre-ordered through AT&T, but I received my iPhone 6S 64G in Rose Gold ON the launch date, around 10:10am. I see some of you ordered the exact same phone & didn't get it on the launch date & that makes no sense.
Since the iPhone 3GS model, my husband always pre-orders my new iPhone through AT&T & I have always received it on the day of the launch via Fed Ex. After looking at a few of the screenshots, I can tell you that, no, he didn't order mine any earlier than some of you did. If anything, he placed his order almost 8-10 hours later than most who posted order screen shots here, placing the order at 5:45pm on September 12th. So I'm aghast that some of you haven't gotten your iPhone 6s yet...even those who ordered in Rose Gold. The 6s Plus, I can understand the backlog, that was expected, but the 6s? I don't get it.
I may encounter the same issue when the iPhone 7 comes out because that's when I plan on going to the Plus model. Anyway, I hope that you guys either get your orders in soon or that you've already received them.
I can tell you that I like the color, it's more pink than it looks in photos, but not so much so that it stands out. It's kind of a coppery shade, rather than rose gold. I love it though. And yeah, the 6s is a "slightly" bigger. I put a case on it that had more wiggle room on my iPhone 6 & it was snug on the 6s...so yeah, snap on hard cases will probably need to be replaced. You'll want a clear case for this one & ive already ordered 2 for it...using the one for my 6 in the interim.
Also, for some reason this time, swapping all my data, contacts, pics, app especially, over to my 6s...it was a real *** pain this time, not sure why. I did eventually get everything done, but it kind of sucked how much time I had to put into it. Add in that I had to unpair my Apple Watch & then re-pair it with my 6s, that made it almost to nightmare status. It could've just been something stupid I was doing wrong though.
All in all I love the 6s, yes it's fast & the camera is great

Love force touch as well, glad they are incorporating features into the iPhone that are used on the Watch.
Fingers crossed you guys get your phones soon!
