<p style="text-align: center;"></p> <p>On June 7, Apple CEO Steve Jobs introduced the fourth generation iPhone, saying <a alt="((CONLINK|568|iPhone%204%20))" href="">iPhone 4 </a> is "really hot"  and "the biggest leap since the original." Claiming well over 100 new features, Jobs shared his favorites, and we've broken them down to showcase what's new on the iPhone 4. With its new display, camera system with HD video, and video calling, you'll see why this phone is not only the most sophisticated iPhone to date, but also the most data hungry. [Update July 16: <a alt="((CONLINK|779|How%20Apple%20Saved%20$1%20Billion%20on%20iPhone%204%20Problem))" href="">How Apple Saved $1 Billion on iPhone 4 Problem</a> ]</p> <p></p>

Slide 2

<p style="text-align: center;"></p> <p>"This is beyond a doubt the most precise, beautiful thing we've ever made," said Jobs. "It's closest kin is like a beautiful old Leica camera."</p> <p>New design for iPhone 4 means 9.3 mm thick, 24 percent thinner than iPhone 3G S. The new stainless steel band that runs around the device actually contains antennas for Wi-Fi, Bluetooth, GPS, UMTS and GSM, an engineering first.</p> <p></p>

Slide 3

<p style="text-align: center;"></p> <p>Jobs calls the iPhone 4's new <a alt="((CONLINK|570|Retina%20Display))" href="">Retina Display</a> "The best window on the planet." It packs four times the number of pixels in the same amount of space as last year's iPhone 3GS to create the sharpest display available on a phone. The 326 pixel-per-inch resolution is higher than the maximum pixel density that the human retina can differentiate, so text on the new phone is like "looking at a fine printed book," Jobs said. Video and images will also benefit from the super high-res display.</p> <p></p>

Slide 4

<p style="text-align: center;"></p> <p>By pairing Apple's own A4 chip used in the <a href="">iPad</a> with a bigger battery, iPhone 4 delivers 40% more talk time than the 3G from 5 to 7 hours, 10 hours of Wi-Fi browsing  and 10 hours of video.</p> <p></p>

Slide 5

<p style="text-align: center;"></p> <p>The iPhone 4's new gyroscope sensor allows for six-axis motion sensing and is ideal for game applications. The gyroscope joins iPhone's other four sensors: accelerometer, compass, proximity sensor, and ambient light sensor. The new gyro allows displayed objects to rotate a full 360 degrees around a central axis more precisely than ever before.</p> <p></p>

Slide 6

<p style="text-align: center;"></p> <p>New camera system adds a rear facing camera and upgrades both cameras from 3 megapixels to 5, adds 5x digital zoom, and LED built-in flash. With new backside illuminated sensor and other camera system upgrades, users can take better quality photos under more conditions including low light.</p> <p></p>

Slide 7

<p style="text-align: center;"></p> <p>The iPhone 4 records HD video at full 720p at 30 frames per second and has tap to focus, built-in video, one click sharing, and a built-in LED flash. Apple also wrote their own application to adapt iMovie video editing app for iPhone 4.</p> <p></p>

Slide 8

<p style="text-align: center;"></p> <p>The much asked for ability to multitask on the iPhone finally came via Apple's new mobile operating system iOS4. The new OS is for not only the iPhone 4, but the iPad and iPod Touch as well. Along with multitasking, iOS 4 offers a unified mailbox to see all email accounts in one stream and threading to follow or delete an entire conversation, and a "smart" folder system for automatically naming similar apps.</p> <p></p>

Slide 9

<p style="text-align: center;"></p> <p>Bing gets added to iPhone search options along with Yahoo Search and Google, which remains the default search engine across Apple mobile devices.</p> <p></p>

Slide 10

<p style="text-align: center;"></p> <p>The<a alt="((CONLINK|571|%20iBooks))" href=""> iBooks</a> app and its associated iBookstore will soon be available on all three mobile devices including the iPhone. One book can be downloaded to multiple devices with no extra charges. Bookmarks and notes are automatically synchronized across devices for seamless reading experience.</p> <p></p>

Slide 11

<p style="text-align: center;"></p> <p>App users will start seeing iAds July 1 on all iOS devices. While this may not sound like good news, Jobs said iAds are necessary to help developers continue to create free and low cost apps. He also said iAds will not "hijack" users, that is if users click on iAds, they will stay within the apps.</p> <p></p>

Slide 12

<p style="text-align: center;"></p> <p>And "one more thing," only for iPhone 4 users, FaceTime video calling over Wi-Fi. Two cameras make this particularly engaging: people can switch between front and rear facing cameras to give their calling partner a view of themselves or what they're looking at. Jobs said Apple will have to work with cell phone providers to make FaceTime work over 3G.</p> <p> </p>
