Steve Jobs introduced the iPhone 4 last day, which he claims offers over 100 new features, though he would focus on only a handful for the keynote. The iPhone 4 looks like the iPhone prototype obtained under questionable circumstances by Gizmodo: stainless steel casing, all-glass front, and a design Jobs describes as the thinnest smartphone on the planet: almost 25 percent thinner than the iPhone 3GS.. Unlike previous iPhones, the iPhone 4 will have volume controls on the side of the phone along with an accessible microSIM tray. The iPhone 4 features a front-facing camera, and the back sports a microphone, 30pin connector for docking, and a speaker, while the top sports a second microphone for noise cancellation, sleep/wake button, and a headset input.

Jobs went on to highlight the bands around the side of the iPhone 4 that caused much speculation in the wake of the leaked prototypes. Jobs identified them as part of the phone’s antenna system, saying the stainless steel band is also a primarily structural element of the device. The antenna supports all the iPhone 4’s wireless capability, from 3G to Wi-Fi to Bluetooth to GPS along with cellular communications.

iPhone 4: Retina Display
The iPhone 4 will also sport what Jobs described as a “retina display” with four times the pixel density of a typical LCD display at a whopping 326 pixels per inch—by far denser than anything else in the consumer electronics market. The result is a 3.5-inch display with a native resolution of 960 by 640 pixels that is actually a higher resolution than the typical human eye is capable of perceiving, when held at a distance of just 10 to 12 inches. Jobs claims the iPhone 4’s display winds up looking like a high quality printed book (albeit that emits light!) rather than a blocky pixellated grid. The iPhone OS automatically handles rendering text and controls at the higher resolution for the iPhone 4, so developers don’t need to do anything to update their applications to look good on the new display…but, of course, if developers want to add higher-resolution graphics to their apps, they will look stunning on the iPhone 4.

iPhone 4: A4 Chip and Gyroscope
The iPhone 4 will also feature an Apple-designed A4 CPU, following along the lines of the processor powering the iPad. Jobs said the A4 processor improved power management, so the iPhone 4 will manage 40 percent more talk time on 3G networks (up to 7 hours), or up to 6 hours of 3G Web browsing or 10 hours of Wi-Fi browsing. The device can also play up to 10 hours of video, 40 hours of music, and should have an standby time of up to 300 hours. The iPhone 4 will also pack up to 32 GB of onboard flash storage, and will offer quad-band HSDPA/HSUPA for mobile broadband speeds up to 7.2Mbps downstream, 4.8Mbps upstream…assuming carrier networks support that technology. The iPhone 4 will also support 802.11n Wi-Fi, assisted GPS, Bluetooth, and packs and accelerometer, compass, proximity sensor, and an ambient light sensor,. The iPhone 4 also sports a gyroscope, which enables six-axis motion sensing…just like a game controller, and iPhone OS 4 will offer developer APIs to leverage the gyroscope: Jobs envisions the gyroscope enabling whole new types of mobile gaming.

iPhone 4: Camera & iMovie
The iPhone 4 will feature a 5 megapixel camera with a backside-illuminated sensor, which Jobs says increases the amount of light captured by the sensor, resulting in better photographs, particularly in low-light situations. The camera will also record HD video at 720p resolution and 30 frames per second, and the LED flash can be used to light video as well. Like the iPhone 3GS, the iPhone 4 will feature in-phone video editing and enable users to share video the the Internet (think Facebook and YouTube). However, Apple is pushing the video editing envelope with a new iMovie application for iPhone, that enables users to assemble and trim clips and record directly into an iMovie timeline. Users can also add camera photos to their movies (complete with the pan-and-scan Ken Burns effect), and iMovie for iPhone will enable users to add titles and transitions to their videos. The iPhone 4 camera embeds geolocation information in video; iMovie for iPhone can optional display display that information. Users can also add music as a soundtrack to their video, and select from a number of pre-generated themes. iMovie for iPhone will be available as a separate purchase from the App Store for $4.99.

iPhone 4: Bing
Among new features in iOS 4 will be an option to use Microsoft’s Bing as a default search engine; Google will still be the iPhone’s default search, but Yahoo and Bing-powered searches will be available as options. Note that Bing will be taking over the back end for Yahoo’s search services later this year.

iBooks for iPhone
Apple also announced a version of iBooks will be available for iPhone, with feature parity to the iPad edition (complete with previously-announced PDF and annotations support). The applications will be able to synchronize across devices, so users will be able to start reading an iBook on an iPad, then pick up at the same spot on the iPhone. Users will be able to download purchased books to all their supported devices at no extra charge.

No Longer iPhone OS 4: iOS 4

Since it won’t do to have an iPad running something called “iPhone OS,” Apple has decided to rename its mobile device operating system to simply “iOS 4,” encompassing all its mobile devices: the iPhone, the iPad, and the iPod touch. iOS 4 will have the features Apple outlined back in April, including a form of multitasking support (so applications like Pandora can stream music in the background while an iPhone user, say, surfs the Web in Safari), a unified Mail inbox that supports multiple services, home screen folders, a Game Center, and improved support for Microsoft Exchange and enterprise users. However, developers will probably be more intrigued by a boatload of new APIs and significantly deepened features. Developers at WWDC will be able to set hands on a release candidate today.

iAds
Jobs also took a moment to highlight Apple’s new in-application advertising platform iAds: according to Jobs, Apple is developing iAds as a revenue channel for developers so they can earn money from applications in ways other than direct sales to users. As outlined last April, Apple is aiming for high amounts of interactivity and engagement with iAds, building on HTML5 technologies rather than the still-industry-standard Adobe Flash. Apple will host all the advertising and handle ad sales, so all applications developers have to do is specify where in the applications the ads should be placed, then collect 60 percent of the revenue from placements in their applications. Apple has only been selling iAds for about two months—they should go live Jule 1—and so far has many major brands on board, including Disney (Jobs is Disney’s biggest single shareholder, remember), Target, Best Buy, Geico, DirecTV, and other major brands. Unlike traditional banner ads that eject users from applications out into Web browsers, iAds run without exiting a user’s application, providing an interactive experience without causing people to leave apps, or lose work or messages: the goal is an engaging experience that users know is “safe” regardless of the app they’re using.

Video Calling
Of course, that front-facing camera in the iPhone 4 exists for one and only one purpose: video calls. Jobs demonstrated what Apple is dubbing FaceTime video calling with the iPhone 4. The feature will initially be Wi-Fi only and operate iPhone 4 devices—no word in whether FaceTime will support, say, desktops or notebooks equipped with cameras. Users will be able to switch to the rear-mounted 5 megapixel camera on the iPhone 4 to let callers see what they’re seeing, or stick with the front-facing camera for face-to-face chat. Jobs says Apple plans to work with mobile operators to make FaceTime available over 3G data services. Apple says it plans to ship millions of FaceTime-capable devices this year—and if current iPhone sales are any indicator, they’re right—so iPhone 4 users will have plenty of people to talk to. (How far off is an app called FaceTime Roulette?)

Apple says the technology behind FaceTime will be come an industry standard, and will be supported by other devices and services.

iPhone 4 Pricing and Availability
The iPhone 4 will be available June 24 in black or white, with pricing set at $199 for a 16 GB model and $299 for a 32 GB model: those price points match the iPhone 3GS. Initial availability will be the United States, France, Germany, Japan, and the United Kingdom.

In the United States AT&T will enable any iPhone user whose contract expires in 2010 to upgrade to the iPhone 4 for $199 or $299 (for the 16 GB or 32 GB model) if users top off their contracts for another two years of service.

Apple plans to continue selling the iPhone 3GS, with the 8 GB model going for $99.

Pre-orders for the iPhone 4 will open on June 15.

Apple plans to begin offering the iPhone 4 in 18 more countries in July, followed by 24 additional countries in August and 40 more countries in September.

Apple will offer a selection of accessories, including a $29 dock and a “bumper” case in various colors.

iOS 4 Availability
Apple’s iOS 4 will ship standard on new iPhone 4 handsets. Apple plans to make iOS 4 available on June 21 for the iPhone 3GS, iPhone 3G, and iPod touch—although there will be some limitations and some iOS 4 features wont be supported on older handsets. (For instance, multitasking will not be supported on the original iPhone 3G. Apple’s original EDGE-only iPhone, released in 2007, won’t support iOS 4 at all.)

Steve Jobs tweets iPhone 4 recall possible: It may all boil down to iOS 4.0.1 In the ever expanding world of “Oh man my iPhone 4 is messed up!”, Steve Jobs himself, the king, tweeted that an iPhone recall is likely. What Steve Jobs tweeted is “We may have to recall the new iPhone. This I did not expect.” No kidding he didn’t expect this, but given that nothing has gone right from the first day of iPhone 4 pre-orders, the yellow dot, and then the signal problem related probably in part to the hardware and definitely to some degree iOS 4, you kinda had to expect more was coming.

What this tweet means most likely is that if the iOS 4 update expected to come out Monday, June 28, 2010 – or shortly after – does not fix the problem then Apple will recall the iPhone 4. What is almost certainly going to happen is that iOS 4.0.1 is not going to fix the reception problem because it is more pronounced on the
iPhone 4 than it is on the iPhone 3GS or other upgraded devices. If iOS 4.0.1 does sufficiently do the trick then that will rock, but right now keeping upbeat about the iPhone 4 is getting tougher to do.

More than likely sometime by the end of this week it is going to be very clear whether or not iOS 4 works the trick or not. If not, iPhone 4 users will be able to return their phones and Apple will fix the problem as quickly as possible and get them back in the hands of their owners working (hopefully) up to the specs outlined at WWDC 2010 and everyone will be happy exceptJobs who will have egg on his and less money to play with. A few developers that find themselves filing for unemployment may be ticked off too.

The big question that no one has answered yet which is intriguing, is what are people going to do while their iPhone 4 is being repaired – assuming there is a recall? Many people have a second cell they can use or can still strong arm their kid and “liberate” theirs, but what about people that don’t have those options who maybe traded their iPhone 3GS in? What are they going to do? Is Apple going to give them some kind of loaner until they get their iPhone 4 back?

It’s new ground for Apple, and had this been an iPad or iPod issue they could easily say people can make it a couple weeks without those devices, but a phone? Especially when so many people do not have landlines anymore, or people that only have one phone at their disposal at a time, this is a pretty valid question. Whatever the answer is Apple is sure to come up with one and get the iPhone recalled, fixed, and returned if it winds up being necessary. At least they are doing something instead of sticking by the “Just avoid holding it that way” non-solution.
