The new Apple iPhone 4 of 2010 is the equivalent of the iPhone in 2007 in terms of pushing the envelope on what a mobile phone can do. There's simply nothing the Big Five has at the moment to even approach it in its totality.
What's New and Better?
First and foremost is the display that Apple brands as the Retina Display. While the first iPhone created a sensation with its landmark UI on a multitouch capacitive touchscreen offering an entirely revolutionary mobile phone experience, the Apple iPhone 4 display boasts of the highest 960 x 640 resolution on the same 3.5-inch OLED display footprint.
This results in a denser dot pitch than any touchscreen on the planet. If you have raved about the iPhone display before, this one has 4X more pixels per inch which at 326 dots/inch, matches the finest printing on earth.
This is no mere HD level display as comparative tests reveal no visible pixilation even on a fully zoomed-out page. In addition, its scratch resistant screen comes from its black aluminosilicate that's 30X harder than the plastic on previous iPhones.
This is the first mobile phone to sport a built-in gyroscope that, as any NASA or aeronautic engineer knows, provides the highest precision movement tracking ever invented. It provides 3-axis detection for pitch, roll and yaw which, coupled with the gravity accelerometer, gives the iPhone a 6-axis motion sensing.
Under the hood is the now famous Apple A4 chip which houses a Cortex-A8 CPU paired with a PowerVR SGX 535 HD graphics accelerator and two 128 MB DDR SDRAM chips for its system memory. Because they are all housed in one chip, the handset processes even faster.
This efficient chip and memory architecture, together with a more power-efficient OLED display that has no backlighting and a 16% larger battery result in a longer battery life. Talk times over 3G is a generous 7 hours with music playback for up to 40 hours and standby at 300 hours.
iPhone users have long suffered its mediocre camera but the Apple iPhone 4 camera redeems itself. With a bigger lens and CMOS sensor even in the same 5 megapixel resolution, you get higher ISO sensitivity allowing better shots on low light even it if has LED flash. It features autofocus and touchfocus as well as geo tagging and 720p HD video recording at 30fps with LD video light.
What Changed?
The first thing that stands out markedly different is the exterior aesthetics. There's a flattened stainless steel frame rimming the entire handset periphery that doesn't bleed to the front. It imparts a sharper edging and a flatter profile that gives it a closer cosmetic affinity with the LG Mini when seen from the sides.
In fact, the curved back side gives way to a flat glassy black surface which highlights the sharp edges of the handset in your grip. And with a 9.3mm waistline, the 4th generation iPhone can claim to be the thinnest touchscreen on the planet, bar none.
What Remains?
The Apple iPhone 4 exudes the same snobbish sophisticated looks and the same solid feel in your hands. You get the same high level of construction and material excellence we've come to associate with the iPhone right from the start. It's 2g heavier and this adds to the solid feel at 137g. It comes with same absence of microSD card slot and the same 16GB and 32GB models.
The display gets the same 16 million colors, accelerometer and proximity sensors, capacitive and multitouch technologies and enjoys the same oleophobic layer for lesser fingerprint attraction. GP
