Scott Forstall hasn't spoken publicly about the iPhone in five years, ever since he was fired from Apple in 2012.

But Forstall, Apple's former SVP of iOS who worked closely alongside Steve Jobs ever since they worked together at NeXT, spoke candidly about the creation of the original Apple handset during a fireside chat with journalist John Markoff Tuesday night at the Computer History Museum in Mountain View, California. 

Forstall was running macOS 10 when the first embers of iPhone started to glow. Apple was actually working on a tablet project at the time, and Forstall recounted that Jobs wanted the tablet to add capacitative touch and multitouch to one-up someone he "hated" who worked at Microsoft.

"It began because Steve hated this guy at Microsoft. That is the actual origin," Forstall said, also adding this person wasn't Bill Gates. 

After hearing this person brag about the work Microsoft was doing on tablets, "Steve came in on a Monday, there was a set of expletives and then, 'Let's show them how it's really done." 

Jobs was adamant about jettisoning any stylus, and set the hardware team to work developing a multi-touch tablet. 

Part of the impetus to create the iPhone too was to develop a product that would overtake iPod, which accounted for half of Apple's sales at the time, Forstall said. This was especially important as Apple was transforming from a computing company into a consumer electronics company.

"We were always looking at what would overtake iPod. What would cannibalize that," he said. "The one thing that seemed like it was was phones. Everyone was using phones."

The idea was nascent until both were having lunch and using their phones. "We hated them," Forstall said, and so it seemed did everyone else around them.

"No one seemed like it was a pleasurable thing to use a phone, but it's a nice thing for communication," Forstall said. 

It occurred to them to take the demo that was being developed for multitouch on the tablet and shrink it to a device that could fit in a pocket, still using the same touch technology. They did just that.

"The second you saw this demo, you knew this was it," Forstall said. "This was the way a phone had to behave."

Jobs agreed, according to Forstall: "Steve said, 'Put the tablet on hold, let's build a phone. Let's build a phone based on multitouch.' And that's what we did." 

Years of work on Project Purple, the codename for Apple's phone project, led to the raucous first iPhone reveal in 2007. Forstall commented on the negative reception to the device, which broke from any phone that had been built before but was also held to those phones' standards.

"When the original iPhone came out, the reviews didn't get it," he said. "The reviews talked about the number of clicks – 'Oh, to send an email, it takes you six taps or something.' 

"And so it was being compared against other smartphones of the time, BlackBerry et. al., according to the metrics people thought were important at the time. They didn't get it. What they didn't get was we were changing the entire paradigm. We were changing the entire way things were done."

He said initial "sales were nice," but not to the level he expected after the amazement he experienced after that first demo and using the first working prototype. 

But Forstall "knew it was going to be huge", especially after spending time with one in the real world, when he and Jobs were the only people to have iPhones before the device was unveiled. 

"It never felt like work to use it," he said of the iPhone. "It always felt amazing. It always felt special."

He also briefly touched on skeuomorphic design, a realistic style that dictated Apple software for years before Jony Ive took over.

"I had never heard of skeuomorphism," Forstall said. "When I look at design – when I look at good design – it's approachable, friendly, you can use it without a manual. It's fun. 

"We talked a lot about photo-illustrative design. It was infused into the design sense of Apple by Steve Jobs since the original Mac. We used these design philosophies. It doesn't mean we loved it, or loved every single part of it. We know it worked. How do we know it worked? You just have to watch people use it."

Forstall, who has spent the years since leaving Apple producing award-winning Broadway shows, advising startups and coming face-to-face with sharks while spear fishing, said he's not currently building a device himself like Android co-founder Andy Rubin has done with the Essential Phone.

Hearing Forstall talk about creating the first iPhone is apropos as this year marks the device's 10th anniversary. The iPhone is expected to go through a significant redesign with the iPhone 8, which will likely launch in September. It's then we'll see just how far the iPhone has come in the 10 years since Steve Jobs unveiled the first one to the world on a keynote stage. 

Forstall spoke with what seemed like genuine delight about his time at Apple, creating the iPhone and especially about working with and knowing Jobs, who passed away in 2011. 

He relayed anecdotes of Jobs insisting on paying for lunch, even though his salary was $1 a year, of flying with him to Las Vegas to demo the first iPhone to the CEO of Singular, and of Jobs helping Forstall recover when he was in the hospital, his body ravaged by a virus. Jobs was compassionate, dedicated and funny, Forstall said, as well as famously driven and demanding.

"Steve was a unique person on this planet," Forstall said. "[He was] the most intense person I’ve know. I've met a number of world leaders and I can tell you having dinner with a world leader is more relaxing than lunch on Tuesday with Steve."
