The big day is finally here. We're counting down to the start of Apple's big event, which is set to kick off at 1 p.m. ET/ 10 a.m. PT. Stay with ABC News for live updates.
While Apple's is keeping today's agenda under wraps, many people are expecting to see a new 4-inch iPhone boasting some of the internal improvements from Apple's iPhone 6 and iPhone 6s. The rumored new device would be about the same size as an iPhone 5s but would pack a faster processor, photo and video upgrades and Apple Pay capability, according to reports.
It's a big week for Apple. Today's event comes one day before Apple and the FBI are set to meet in court regarding an ongoing battle over unlocking an iPhone that belonged to one of the San Bernardino shooters.
We're starting with a video featuring "40 Years in 40 Seconds," running through some of Apple's highlights, from the Lisa computer to the iPod and iPhone and finally...today.
"Normally we don't spend a lot of time looking back, but yes, we are about to celebrate Apple's 40th birthday on April 1st," Tim Cook says.
Tim Cook is touting a recent milestone -- There are now one billion Apple devices in use around the world.
Tim Cook begins by addressing the encryption battle with the FBI.
"We built the iPhone for you, our customers, and we know it is a deeply personal device. For many of us the i[hone is an extension of ourselves," Tim Cook says.
"We need to decide as a nation how much power the government should have over our data and over our privacy. I have been humbled and deeply grateful for the outpouring of support we have received from Americans across the country from all walks of life," he said, adding the company never expected to be "at odds with our own government."
“This is an issue that impacts all of us and we will not shrink from this responsibility,” Cook said before throwing to an environmental announcement.
Apple is beginning with some environmental announcements. Among them: 93 percent of Apple's facilities run on renewable energy now.
We're now meeting a research and design project called Liam that is designed to deconstruct old iPhones, allowing certain materials inside to be repurposed.
Lisa Jackson, Apple's VP for environmental issues, announces Apple Renew, a program that lets users take old products to an Apple store or send them in for free by printing a pre-paid label at apple.com/recycling.
Jeff Williams is now on stage discussing ResearchKit, which allows researchers to gather health data from willing participants, allowing them to gain new insights into medical research.
One year later: Apple is sharing some success stories: A Parkinson's study became the biggest ever in 24 hours. An EpiWatch app can be used to track seizures and triggers, another study is working on a way to detect autism at an even earlier age.
Apple is launching CareKit today. It's a framework for developers to build apps and "empower people to take a more active role in their care." The first app being released today is for Parkinson's. Six hospitals will start using it right away with their patients, Williams says.
We're getting some new Apple Watch....bands.
Beginning today, the Apple Watch will start at $299. That's a $50 price cut.
We're now hearing about Apple TV. More than 5,000 apps so far.
The major updates:
Siri can now search apps even better.
You can now arrange your folders on the screen.
You can dictate information such as your username and password.
The free update is available today.
Onto the iPhones.... Apple sold 30 million 4-inch iPhones last year.
"Some people asked us, some people even pleaded with us to please keep the 4-inch products in our line-up," Greg Joswiak says.
Introducing the iPhone SE.... "At the heart is our chips, our Apple A9 chip." It's nearly double the speed of the 5S.
Basically: The new iPhone looks like a 5 but has the brains of an iPhone 6 and iPhone 6s.
-Live Photos (An update from the iPhone 6s that captures the moments before and after a photo is taken to create neat photo memories.)
-12 megapixel camera
-True tone flash
-Built-in Apple Pay
-Panorama up to 63 MP
The iPhone SE starts at $399.
Orders begin this Thursday, March 24. The new phone will be available March 31. Apple expects to be in more than 100 countries by the end of May.
W're discussing iOS 9.3 now. Expect night shift -- a feature that removes blue light in the evening and helps you sleep easier. Notes app can also be protected by a passcode/finger print, making sure no one gets access to your most personal notes.
Get ready to update your iPhone -- iOS 9.3 is available today. Tim Cook says he's "looking forward to sleeping better" thanks to night shift.
Onto the iPads... over to Phil Schiller, SVP of marketing
Phil is discussing how much people love the 12.9-inch iPad Pro and Apple Pencil.
Introducing the second member of the iPad Pro family... It's based around a 9.7-inch retina display.
The size is significant -- Apple has sold more than 200 million iPads with a 9.7-inch display, so the new iPad Pro is designed to appeal to those people who love the size but are ready for an upgrade.
"Customers love taking photos with their iPads," Schiller says.
The new iPad comes in four finishes -- and for the first time ever, rose gold.
Apple is also offering a 12.9-inch iPad Pro with 256GB is $1099. Now, back over to Tim Cook.
Cook says this is probably the last product announcement people will ever hear in this room on the Cupertino campus. It's the place the iPod and App Store were announced.
Apple's new campus -- the one that looks like a spaceship -- will be ready in 2017.
