As expected, Apple unveiled its new iPhones today at its big event – the iPhone 6s and the iPhone 6s Plus. Surely trying to battle the notion that the “S” versions of iPhones are only minor upgrades, Apple’s adopted the slogan “the only thing that’s changed is everything” for this new set of phones.

The iPhones haven’t changed in size – the 6s is still 4.7 inches and the 6s Plus is 5.5. They do have plenty of hardware improvements, however, including a new 64-bit A9 chip and new ion-strengthened glass.

One of this biggest additions to the new iPhones is 3D touch, which uses pressure to differentiate tapping actions. Basically, the new iPhones will perform different actions based on how hard you press it.

“iPhone 6s and iPhone 6s Plus introduce new ways to navigate and experience iPhone by sensing pressure to enable new gestures — Peek and Pop™ — so you can dip in and out of content without losing your place. Press lightly to Peek at a photo, email, web page or other content, and press a little deeper to Pop into the content itself. With Quick Actions, 3D Touch provides shortcuts to the things you do most, so you can send a message or take a selfie with just a simple press from the Home screen,” says Apple.

Some of the cooler new elements to the iPhone 6s come from upgraded cameras, which are now 12 megapixels on the back and five for the front-facing one.

Live Photos is Apple’s new ‘wow’ feature, and it allows you to tap on a photo and have it animate. These aren’t videos, rather photos that take a little bit before and little bit after the photo in order to create brief moving images. According to Apple, Facebook will begin supporting these soon.

The iPhone 6s now shoots video in 4K, 3840 x 2160 resolution.

And when you’re taking a selfie, the iPhone 6s uses the entire retina display as the flash.

“The only thing that has changed with iPhone 6s and iPhone 6s Plus is everything — 3D Touch lets users interact with iPhone in entirely new and fun ways, and the innovative Live Photos brings your pictures to life,” said Philip Schiller, Apple’s senior vice president of Worldwide Marketing. “These are the most advanced iPhones ever, with 7000 series aluminum, ion-strengthened glass, the new 64-bit A9 chip, 12-megapixel iSight and 5-megapixel FaceTime HD cameras, faster Touch ID, LTE and Wi-Fi. Customers are going to love them.”

Prices start at $199 for the 16GB iPhone 6s on contract. The price increases by $100 as the space doubles, all the way up to 128GB. The iPhone 6s Plus is $100 more than that. Apple is also offering an iPhone upgrade program starting at $32 a month.

The phones will hit Australia, Canada, China, France, Germany, Hong Kong, Japan, New Zealand, Puerto Rico, Singapore, the UK, and the US on Friday, September 25, with pre-orders beginning Saturday, September 12.
