July 03, 2010 By: lilybird Category: iPhone/iPod

Cell phones seem to get sleeker and slimmer by the day, and the Apple iPhone 4 is no exception. Its new design attracts the eye, a design that is appreciably thinner than the iPhone 3GS. Whereas the iPhone 3GS is 12.3mm thick, the iPhone 4 is only 9.3mm deep for a reduction in size of about 24%. Additionally, the iPhone 4 is narrower, measuring 59mm to 62mm. The weight of the iPhone 4 has stayed the same as its predecessor at 136g, but the dimensional alterations lead to a less bulky perception. Of course, the iPhone 4 offers much more than just cosmetic enhancements. What makes this phone so welcome is what has been changed and updated inside of the handset. As with its predecessor, Apple iPhone 4 comes with a 3.5-inch display, but the new phone’s display doubles the resolution – 960-by-640-pixel. At 326 pixels per inch, this means that phone has the highest resolution screen display available on a phone to date.

Also featured on the iPhone 4 is the “Retina display.” The name refers to the fact that the display is greater in number of pixels than the human retina is able to process. The high number of pixels brings a new level of performance in sharpness, clarity, and detail of the images seen on the phone. The in-plane switching (IPS) techniques found on all iMac and iPad displays also appears on the iPhone 4. The bright, lustrous display and its huge viewing angle make images look excellent from any position.

The Apple iPhone 4 contains the company’s A4 CPU. This is the same processor found in the Apple iPad. Running on the iOS 4 operating system, a number of capabilities are available to the Apple iPhone 4. The recently renamed iOS 4 provides the long-awaited multitasking function. Just as with the welcome and long awaited copy and paste feature, Apple has come through by making the multitasking feature operate without a hitch.

Camera and video advancements are also welcome enhancements to the iPhone 4. The primary camera has received a boost from 3 to 5 megapixels. This is accomplished with the same size pixels. Also new is an LED flash, backlit sensor and a 5X integrated zoom. High-def video is now possible at 720p and 30 frames per second. The tap-to-focus feature previously found only on the camera is now included on the video recorder.

To summarize, the Apple iPhone 4, is a must-have for any smartphone lovers. Unlike the previous upgrade (from the iPhone 3G to the 3GS), which saw only slight performance improvements, the iPhone 4 sees significant improvements all round, making it comprehensively better than anything that we have seen before.
