Steve Jobs introduced the iPhone 4 on 7th June, 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.
Retina Display: The iPhone 4 also supports 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. 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.
A4 Chip and Gyroscope: The iPhone 4 also features 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 web browsing or 10 hours of Wi-Fi browsing.
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
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.
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 .
iAds: 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
Video Calling: Of course, that front-facing camera in the iPhone 4 exists for one and only one purpose: video calls. Apple is dubbing FaceTime video calling with the iPhone 4. The feature will initially be Wi-Fi only and operate iPhone 4 devices.
With over 100 new features included in the iPhone iOS4 the iPhone developers are ready in action for app development and have also started app submission to the App store. But what iPhone geeks need to take care is to select the best apps and check the iPhone application reviews for any category before downloading any app.
