Apple introduces iPhone 6

WASHINGTON, Sept. 9 (UPI) -- Apple's big presentation has finally arrived, and tech junkies await their announcement with bated breath.

Among the expected announcements are of course the new iPhone, a mobile payment system and the highly anticipated wearable device.

Follow this space as we track Tuesday's announcement.

1:08 p.m.

Tim Cook: "The biggest advancement in iPhone."

"The iPhone 6 and the iPhone 6 Plus"

With Retina HD screens.

"These are the thinnest iPhones ever made."

It also now has a horizontal home screen mode.

The new chip, A8, will power the iPhone 6 and 6 plus.

New "reachability" gesture, a double-touch on the home button, slides the whole screen down so you can more easily reach the top buttons (for one-handed use).

1:30 p.m.

Apple says it's extended the all-important battery life.

It has also added a new sensor to track not just movement and steps, but also elevation, in case you like to run stairs.

You can now make voice calls over wifi, and it will transfer to the cellular networks seamlessly.

1:35 p.m.

The new camera includes optical image stabilization, faster autofocus, and the kind of focus pixels found in DSLR cameras.

Shot at night using new optical image stabilizers.

Slow motion video now shot at 240 fps.

1:40 p.m.

New prices, available September 19 in the U.S., and 115 countries by the end of the year.

Preorders start Friday, September 12.

1:45 p.m.

iOS 8 will roll out to all compatible devices on September 17.

(And the new iPhone ads feature Jimmy Fallon and Justin Timberlake.)

1:50 p.m.

Tim Cook: "It's so easy to lose your card or have it compromised, it's not wonder people have been dreaming of replacing these for years. But they've all failed."

"This is exactly the kind of problem we love... we've created an entirely new payment process."

"Apple Pay" is a near field communication system using the Touch ID introduced with iPhone 5S.

Credit cards go into Passbook.

Each transaction authorized with a one-time unique number, which generates a dynamic security code to replace the security code on your card. Apple won't get purchase information, and the retailer doesn't get information about the customer.

The credit card number isn't stored on the card, and if you lose your phone, you can use Find My iPhone to suspend payments from your device, so you don't have to cancel your credit cards.

American Express, Mastercard, Visa credit cards. Apple pay will also be useable as a one-touch process online.

2:00 p.m.

"One more thing..."

It's called Apple Watch and, well, it's about time.

Cook: "We set out to make the best watch in the world."

"Works seamlessly with your iPhone and it's also a comprehensive health and fitness device."

The Apple Watch.

"What we didn't do was take the iPhone and shrink the user interface and strap it on your wrist."

The dial on the watch -- the digital crown -- has the extra functionality, like zoom in the map, scroll in a list, without blocking the screen. The crown also works as a home button.

The Apple Watch can talk to another device nearby (send a drawing to a friend, or even share your heartbeat!), can tell the difference between a touch and press, and charges with a MagSafe, wireless charger.

A number of different watch faces (including a smaller size with smaller straps) and six straps to make up three distinct collections: the Apple Watch, the Sport collection and the Apple Watch Edition made of 18 karat gold.

Zoom around home apps, customize watch face, including the colors and to display different information.

"Glances," available from a swipe up from the bottom of the watch screen, include screens you choose, both built-in apps and third-party apps.

Notifications will feel like a tap on your wrist -- it won't be noticeable to people sitting next to you. To view notifications, raise your wrist.

Quick reply, dictation, dictation and Siri are all built into the Apple Watch, as well as customizable animated emoji.

2:30 p.m.

Third party apps, such as American Airlines, Starwood Hotels, Twitter and Pinterest, have already developed rich integrated experiences just for the Watch.

2:40 p.m.

The fitness sensors keeps track of how much you move, how much you stand, and exercise measures brisk activity. The Workout app tracks real-time stats such as calories, distance, pace for workouts, and integrates with the Fitness app on the iPhone to keep track of information over time.
