Steve Jobs unveils the iPhone 4 at WWDC (photos)

Steve Jobs on Monday kicked off the Worldwide Developers Conference, which he says has more than 5,200 attendees from 57 countries this year.
Starting off talking about the iPad, Jobs says Apple has sold more than 2 million iPads in the 59 days since its release.

"It's hard to remember what it was like before iPhone," he says. Apps weren't the same. There was no free market for apps. iPhone changed that in 2007, he says. He says the iPhone 4 is the most exciting thing to happen since the release of the original device in 2007.

Jobs ran through a few of Apple's achievements with the iPhone, saying this version is the best since the original iPhone was unveiled in 2007.

Jobs hinted at the stolen iPhone/Gizmodo fiasco and said we'd all seen it, but that we haven't seen it until we actually see it.

The new retina display is stunning, Steve Jobs says, doing a side-by-side with an iPhone 3GS. They have increased the pixel density, putting four times as many pixels in the same amount of space.
The 3.5-inch display is "better than OLED," he says. Contrast ratio is 800-to-1. iPhone OS 4 makes it so your apps automatically run on the retina display full size, he says.

Jobs showed us the insides of the new device, saying the new iPhone 4 is packed to the gills. He points out they used a micro SIM because it's smaller and they needed the space.

The biggest thing in the iPhone 4 is the battery, Jobs said, and since the battery is bigger and the A4 chip is good at power management. There is 7 hours of talk time, 6 hours of 3G browsing, 10 hours of Wi-Fi browsing, and 300 hours of standby.

The iPhone 4 is just 9.3mm thick, a 24 percent reduction, he said.

Environmental report card: arsenic-, mercury-, BFR-free, he says.

Although RIM continues to hold a large majority of the market, the iPhone changed everything.

Jobs said the iPhone continues to dominate in the mobile market.

As our phones become equipped with more sensors, we are capable of building richer applications, Jobs says, adding that he can't wait to see what developers will do with the iPhone 4.

The new 5MP camera has a 5-times digital zoom, tap to focus, and LED flash built in.

The camera on the new iPhone has gone from 3 MP to 5 MP but keep pixels the same size at 1.75 microns, resulting in some incredibly sharp images.

A 16GB iPhone 4 will be sold for $199 and a 32GB version will be $299.

One of the most requested features of iBooks was to have the capability to view and read PDFs, and that feature is now built in, Jobs said.

Jobs said there are now 225,000 apps in the App Store, and Apple continues to receive about 15,000 apps submissions every week.

Jobs touted the HTML5 standard, saying anyone can write HTML5 apps and have them on iPhone, Mac, iPod, iPod Touch, and iPad.

Netflix CEO Reed Hastings said the iPad app has gone really well, more than 2,000 downloads. But coming this summer, Netflix will be on the iPhone for free.

This is, after all, WWDC, and it's all about the developers, and Jobs very proudly said that Apple has paid out more than $1 billion to developers who have built on the iPhone and iPad platform.
