The iPhone 6S and iPhone 6S Plus look almost exactly the same as their predecessors, the iPhone 6 and 6 Plus, on the outside. But there are plenty of changes, and most aren't visible until you use the phone.
There's one key exception: The addition of a new color: rose gold. Mashable's Christina Warren says the new color is very much like a pink iPhone: "They say it's rose gold, but it's pink."
The other improvements and additions include 3D Touch, which lets you interact with apps in new ways depending on how hard you press on the screen, improved cameras (plus a new way of snapping pictures called Live Photos), and even a more durable aluminum.
Here's our first look at the new iPhones. Check back here for our full hands-on, coming soon.
