Reviewing The Main Specifications Of The Best-Selling iPhone 4

The release of the Apple iPhone 4 last year in June 2010 was certainly a significant event to remember. With the slogan "This changes everything..again", Apple certainly did hit another jackpot with its 4th generation release of its ever popular iPhone. Backtracking a little into the history of the Apple iPhone, Apple has released the last 4 generations of the iPhone over the last 4 years, releasing one each year as follows: the original iPhone in June 2007, iPhone 3G in June 2008, iPhone 3GS in July 2009, and iPhone 4 in June 2010.

So what makes the iPhone 4 so desirable? Let's take it apart and see what this smartphone packs. To start off with on its physical outlooks, the iPhone 4 was designed somewhat differently from its predecessor, the iPhone 3GS. Departing from the rounded back of the iPhone 3GS, the iPhone 4 adopted a flat rectangular block look with rounded edges, and best of all, a stainless steel frame that is responsible for giving this device its new, polished look that is highly desirable to touch. This stainless steel frame also functions as the phone's antenna, a very unique design; though there have been rumours and complaints about edgy antenna reception.

Armed with a LED backlit 3.5-inch touchscreen, to date Apple iPhones have provided users with one of the smoothest and slickest touchscreen experiences. With an Apple A4 processor running at 1GHz and 512MB of RAM, Apple has significantly boosted the speed over its predecessors which also affords the iPhone 4 its smooth, speedy touchscreen experience. One of the strongest features of the iPhone 4 is its record-setting screen resolution of 960x640 pixels. Packing the highest record of 326 ppi (pixels per inch, a measure of image quality), no other smartphone to date or even tablets and monitors for that matter have come close to this. Thus, this 'super' high-definition display is marketed as the "Retina Display", which basically claims to pack as many pixels as the retina in your eye could possibly see for the best visual experience.

Currently running on the latest iOS 4.3.5, Apple iPhone 4 makes full use of Apple's user-friendly and intuitively designed interface, which is probably Apple's hallmark and trademark of fame. Packing flash memory size choices of 16GB and 32GB, there are over 300,000 apps for consumers to select from the App Store, which is also unbeaten to date by its competitors in terms of sheer numbers and selection of apps available.

With a 3-axis gyroscope and accelerometer, the iPhone permits apps to even track motion sensitivity, as used in games or even in sleep cycle alarms in detecting your body movements while sleeping. Though a little weak in its single loudspeaker, its true audio strength only comes in when you hook up some good headphones or output the sound via speaker docks. The iPhone 4 is truly an iPod touch with the phone added in.

With is camera resolution increased from 3 to 5 megapixels, the iPhone 4 offers decent picture-taking capabilities, best of all with its HD video camera capable of capturing 720p at 30fps. Packed with connectivity options ranging from Wi-Fi, Bluetooth, as well as support for HSDPA (also known as 3.5G), the iPhone 4 truly serves much more than just being a phone.  It is also a pocket internet browser, audio and video player, camcorder, e-book reader, gaming device and so on. Its capabilities are practically boundless, limited only by the imagination of app creators.
