Apple Launches Next iPhone: iPhone 4

The new Apple iPhone 4 announced by CEO Steve Jobs at WWDC. Thinnest Smartphone Ever with All-New Design with FaceTime Video Calling, Retina Display, 5 Megapixel Camera & HD Video Recording. Just 9.3 milimeter thick, the iPhone 4 is 24 percent thinner than the previous model. External buttons include a separate volume up and down button, the mute control, and a Micro-SIM tray, in addition to the 30-pin dock connector and a 3.5mm audio jack. An additional noise cancellation microphone is used to suppress unwanted background noise for improved call quality when in loud places. Connectivity-wise, the iPhone 4 supports Bluetooth and WiFi 802.11 b/g/n connectivity (2.4GHz only in the 802.11n mode), in addition to the GPS sensor and quadband GSM/UMTS/HSDPA/HSUPA capable of both 7.2Mbps in the downlink and 5.8Mbps in the uplink.

According to press release, The iPhone 4 sports a scratch-resistant, aluminosilcate glass front and rear surface, “chemically strengthened to be 30 times harder than plastic.” There’s also the familiar stainless steel band running around the side, forged to be five times stronger than standard steel. Jobs called the iPhone 4 “beyond a doubt the most precise things, one of the most beautiful things we’ve ever made.” 
 

The iPhone4 has the same-sized 3.5-inch display like the previous iPhone. However, it incorporates a new display technology that Apple calls Retina Display, which packs in four times the previous iPhone’s pixel density, resulting in a 960×460 pixel resolution and a whopping 326 ppi pixel density. Jobs said during the presentation that 300 ppix is the limit of the human retina when you look at the display this large at 10-12 inches. He said there has never been a display like this on a phone that lets you enjoy “really, really sharp text.” A five-megapixel camera with LED flash is located on the back, a significant improvement over the 3.2-megapixel unit on the iPhone 3GS. The camera has five times digital zoom, records 720p video at 30 frames per second, and supports geolocation-tagged videos and tap-to-focus during video recording. In addition, you can leave LED flash turned on during video recording.
 
The iPhone 4 also has an additional front-facing camera is used for video calls, Jobs said and then went on to demo a new video conferencing app called FaceTime. It requires no setup and supports in-call switching between front- or back-facing camera. However, video calling will be possible only via WiFi, at least this year until Apple “works a little bit with cellular providers” to make video conferencing on the go work over 3G cellular networks as well. 
 

iPhone 4 has a brand new iMovie app, though its cost $5 to download, that lets you edit your HD clips with themes, transitions, titles, and music all directly on the device. You can also pinch to change the scale of timeline, export your clips to 360p, 520p, and 720p, switch themes on the fly, add photos to your movies, and more. 

iPhone 4 runs Apple’s speedy A4 chip, presumably the same or a slightly varied piece of silicon that’s also powering the iPad. The chip allows the phone to multitask efficiently and conserve battery while running your apps significantly faster. The iPhone 4 comes with a bigger battery that files as its biggest component. Together, a larger battery and the power-savvy A4 chip deliver seven hours of talk time, six hours of 3G browsing, ten hours of WiFi browsing, ten hours of video playback, forty hours of music, and three hundred hours of standby. A new gyro sensor works in conjunction with the existing accelerometer sensor to provide six-axis motion sensing, “rotation about gravity,” and deliver pitch, roll, and yaw via new CoreMotion APIs found in the iPhone OS 4 software that has been renamed into just iOS 4 at the event.

The iOS 4 will add Bing as a third search option in Safari. Another surprise is the iBooks app that will be provided as a free iPhone download by the end of the month. The software will let you download an e-book once and share it across iPads, iPod touches, and iPhones at no extra charge. Like the Kindle app, the iBooks app automatically syncs the last page read, notes, and your bookmarks across all three devices. You can also open open PDFs attached to email messages directly in the iBooks app. The app also takes advantage of the new Retina Display, resulting in sharp text and crisp, high-resolution images.

The iPhone 4 goes on sale June 24 in the US, UK, France, Germany, and Japan, and then arriving to 88 countries by the end of September. It’ll arrive by the end of July to Australia, Austria, Belgium, Canada, Denmark, Finland, Hong Kong, Ireland, Italy, Luxembourg, Netherlands, Norway, New Zealand, Singapore, South Korea, Spain, Sweden and Switzerland. 

In USA, AT&T is also the only company to announce the iPhone 4 prices. The iPhone 4 16GB will cost you 199 USD while the doubled memory capacity iPhone 4 32GB will cost you another 299 USD and a new 2-year contract with AT&T comes along with the phone. In Germany, too. T-Mobile remains the only operator there to have a contract with Apple. As for Japan, if you live there, you'll have to wait for 24 June to come. This is the day when the iPhone 4 will show up in SoftBank's stores.

France have a much wider choice of carriers: Orange, SFR, and Bouygues Telecom are all rumored to be offering the Apple iPhone 4. So far, Orange is the only company to officially confirm that, but official statements from the other carriers are expected soon. There are three companies currently serving iPhones in the UK and all three of them will get the upcoming iPhone 4: O2, Orange and Vodafone. Though T-Mobile UK will also deliver the iPhone 4 as well. Three operators Rogers, TELUS and Bell in Canada will get Apple's latest smartphone sometime in July. In India Vodafone will launch it in coming months.
