APPLE IPHONE 4 REVIEWS AND DISPLAY

The iPhone 4 is now boxier, with the rear side now flat, instead of rounded. It will keep the 3.5-inch display diagonal, but will quadruple the pixels to 640x960, making it the highest-resolution screen on a smartphone to date. Apple actually calls the new screen Retina Display, because it shows 326 pixels per inch, while the human eye can only distinguish around 300 ppi. In addition, the screen will utilize the LCD IPS technology (same as in the iPad). The other new stuff includes a front-facing video call camera, 5MP main camera lens with LED flash and 720p HD video recording, Micro-SIM slot, instead of ordinary SIM, a secondary mic for noise-cancellation and a lot of other new features.
          
Plenty of things can change over the course of three years in the mobile world as technology seems to leap new heights constantly when devices are being packed with intricate hardware and an accompanying platform experience to make it gratifying. The smartphone landscape changed heavily when the original iPhone first came to fruition back in 2007 to a wide audience that was initially skeptical in how an unknown figure in the mobile community could change the game. The events that unfolded over the last few years tell the true telling of how the iPhone substantially affected the industry with its ground breaking performance. However, we've seen the handset don two additional makeovers, the iPhone 3G and 3GS, that some still argue to not necessarily accompany that reinvention that came along with the original's release. It's summer and Apple's tradition of releasing a new version of the iPhone each year continues as the world has been well informed regarding the highly prized product which received plenty of attention in the last few months leading up to its release due to a bevy of leaks. It's here! Now and in the flesh! But will it be enough to withstand the onslaught of competition that's currently catching up, consistently evolving,  and closing the gap?

Quickly gazing at the smartphone for the very first time, it tastefully can be seen that Apple decided to go back to the drawing board this time around as it sheds the previous look of the iPhone 3GS with a totally new one. Clearly it looks like an iPhone from afar, but upon closer inspection, you can meticulously feel the love that went into building and crafting this device together. Essentially the handset is encased by two pieces of strong glass which are held together by the brushed stainless steel band – used also to help aid the handset in receiving better cellular radio connections. The smooth glass found in the back replaces the glossy plastic one that's been in use with the previous two iterations and essentially make it flat – even the lens on the camera follows the flush pattern. As much as we adore the strength of the material and radiance it offers, it's a prone for all the nasty baddies out there that take away from its shiny luster. Additionally, when holding it for the first time after being accustomed to the curved backing of the iPhone 3GS, it doesn't hug your hand as good as we'd like it to – still, it didn't take too long before we got used to it. Clearly it's one of the thinnest smartphones (it's actually said to be the thinnest) we've seen to date. It's also narrower than the previous versions of the product. Following suit, the iPhone 4's construction feels solid throughout every nook and cranny as there is no denying that it can repel the wear and tear of age. Flaunting an almost identical weight to its older sibling found with the iPhone 3GS, it's evenly balanced and makes the phone feel even more durable, however, we'd be appalled to think about the consequences of dropping it. Overall, the fresh look of the iPhone 4 has a somewhat nostalgic tone as it makes us harken back to the 80s when Sony's beta-max units were all the rage with their metallic exterior and knobs jutting out prominently. Its industrial design provides a modern update which tastefully exemplifies an old time favorite look that will surely keep gazers close-by.

When you quickly look at the landscape of high-end smartphones currently on the market, they all mostly sport WVGA displays and utilize a range of technologies – such as LCD, AMOLED, or Super AMOLED. As we tend to see Apple stick with something very unique for their handset, they decided to employ an LED back-lit IPS LCD display packing a monster crunching 640x960 pixels resolution which quickly became more known as the “Retina Display.” At the same time, Apple opted to keep its screen size at 3.5” which naturally increases its pixel density immensely – making it THE most detailed screen we've seen to date. Compared to the WVGA displays in use with some of its competitors, the “Retina Display” on the iPhone 4 pack a wallop by making even the tiniest of text look detailed upon closer inspection. Honestly, we were able to clearly see the difference between the iPhone 3GS and 4 when looking at the display from a distance of a foot – text on the iPhone 4 was much smoother and didn't look fuzzy like on the 3GS. Colors continue to shine as it boasts support for the same 16 million colors we were first introduced to back with the original. And just like all of the previous models, the capacitive display was responsive to the touch which made navigating around the interface a breeze. Still being one of the few handsets to utilize an oleophobic coating on the touchscreen, we're always glad to see it looking so fresh and pristine every time we take it out of our pockets. Generally using any handset outdoors in direct sunlight can become a nightmare – making some look quite unviewable even when brightness is set to its max. Thankfully, it steers ahead of the pack as it manages to shine brightly in almost any lighting conditions – even in direct sunlight. In addition, the utilized IPS technology comes along with some pretty wide viewing angles. However, we still feel strongly that Super AMOLED displays provide for richer looking colors, which can even fool some out there to believe that the display is turned off when the color black is present.
                                  
This time around, Apple decided to make the single home button feel more springy than what we experienced previously. In fact, this actually applies to all of the physical hardware buttons found on the phone as every single one of them has that solid tactile feel. The left part of the phone houses the all too standard vibrate switch and volume rocker – the latter being two distinct and separate circular sized buttons. Jumping to the top, we have the 3.5mm headset jack and dedicated power button while on the right side you'll find the micro SIM card slot. On the bottom of the phone, you'll notice the  speakers and Apple's proprietary connection port. Flipping it over to its rear, the only thing you'll find is the 5-megapixel auto-focus camera with flash and the usual mirror looking Apple logo that elegantly brands the smartphone. Finally, in the front and next to the main speaker is the 0.3-megapixel front facing camera.

APPLE IPHONE 4 SPECS, REVIEWS AND FEATURES

The iPhone 4 is a touchscreen smartphone developed by Apple. It is the fourth generation of iPhone, and successor to the iPhone 3GS. It is particularly marketed for video calling (marketed by Apple as FaceTime), consumption of media such as books and periodicals, movies, music, and games, and for general web and e-mail access. It was announced on June 7, 2010, at the WWDC 2010 held at the Moscone Center, San Francisco,[6] and was released on June 24, 2010, in the United States, the United Kingdom, France, Germany and Japan.

The iPhone 4 runs Apple's iOS operating system, the same operating system as used on previous iPhones, the iPad, and the iPod Touch. It is primarily controlled by a user's fingertips on the multi-touch display, which is sensitive to fingertip contact.

The most noticeable difference between the iPhone 4 and its predecessors is the new design, which incorporates an uninsulated stainless steel frame that acts as the device's antenna. The internal components of the device are situated between two panels of chemically strengthened aluminosilicate glass.[7] It has an Apple A4 processor and 512 MB of eDRAM, twice that of its predecessor and four times that of the original iPhone. Its 3.5-inch (89 mm) LED backlit liquid crystal display with a 960×640 pixel resolution is marketed as the "Retina Display".

The latest operating system release is iOS 4.3.3 (for GSM) and 4.2.8 (for CDMA).

Prior to the official unveiling of the iPhone 4 on June 7, 2010, two prototypes were brought to the attention of the media, breaching Apple's normally secretive development process. Many of the speculations regarding technical specifications proved accurate.

The iPhone 4 features a redesigned structure, designed by Jonathan Ive. Most notably, the bulges of the back panel as well as the band between the front and back are gone and have been replaced with flattened surfaces. The redesign reflects the utilitarianism and uniformity of existing Apple products, such as the iPad and the iMac. From the side, the metal structure most resembles the original iPhone, but from the rear, the plastic evokes the iPhone 3G and 3GS. The general layout of the device remains the same. The overall dimensions of the iPhone 4 have been reduced from its predecessor. It is 4.5 inches (110 mm) high, 2.31 inches (59 mm) wide, and 0.37 inches (9.4 mm) deep, compared to the iPhone 3GS, which is 4.55 inches (116 mm) high, 2.44 inches (62 mm) wide, and 0.48 inches (12 mm) deep; making the iPhone 4 24% thinner than its predecessor, the iPhone 3GS. Steve Jobs claims that it is “the thinnest smartphone on the planet". The reduced size of the device is primarily due to the externally placed antenna.

The iPhone 4 is structured around a stainless steel frame that wraps around the edge of the phone, acting both as the primary structure for the device and as the iPhone 4's antennas. This metal band features two slits on the GSM version of the phone, one at the lower left, and one at the top (and a fake slit along the lower right, to cosmetically mirror the one at the lower left) that divide the band into two antenna sections: the left section of the band serves as the Bluetooth, Wi-Fi, and GPS antenna, and the right and lower sections of the band act as the antenna for GSM and UMTS connectivity. On the CDMA version of the phone, however, there are four slits in the metal band. Two at the top (on the left and right) and two at the bottom. This divides the metal band into four different segments, which like the GSM version of the phone, serves as different antennas for connectivity. The top portion of the band (divided by the top left and right slits) is for connecting to the CDMA network. The left portion of the metal band is for Bluetooth, Wi-Fi, and GPS just like the GSM version. The right side is not an antenna, but serves to cosmetically mirror the left side and also to create a similar look to the GSM version of the phone.

The internal components are situated between two panels of aluminosilicate glass, described by Apple as being "chemically strengthened to be 20 times stiffer and 30 times harder than plastic," theoretically allowing it to be more scratch resistant and durable than the previous models.
