The iPhone 4 is one of a product designed and marketed by Apple Inc. which brings the company, the users and the world into a new dimension. There have been four generations of iPhone. The very first model of the iPhone is called iPhone. The first iPhone was released to the market in mid of 2007. The second generation is called iPhone 3G (released on mid of 2008), follow by iPhone 3GS (released on mid of 2009) and the current iPhone 4 (released on mid of 2010).
The iPhone is not a normal basic phone that you can only call and receiving a call but it is a smartphone. This meaning that iPhone is a combination of basic phone, internet and multimedia-enabled smartphone including camera, text messaging, visual voicemail, portable media player, WIFI connection, and an Internet client with email, web browsing and many more. iphone 11 pro max
One of the most important selling points and dominant feature of the iPhone 4 is the Retina capacitive touch screen. This Retina screen is the sharpest, most vibrant, highest-resolution of 640 x 960 at 326 ppi with scratch-resistant glass phone screen ever. The capacitive touch screen is designed for a bare finger, or multiple fingers for multi-touch sensing. The touch and gesture features of the iPhone given not only sensitivity but the most precision finger touch input. It gives the users feeling like the iPhone is so intelligent which the iPhone knows when you want to switching/swiping between the pages only and when you want to open an application (apps).
I believe that most of you know that one of the iPhone 4 impressive capabilities is the “pinching” gesture. It zoom in and out of web pages and photos which is done by placing two fingers on the screen and spreading them farther apart or bringing them closer together. Secondly, the accuracy of text input through touching the virtual keyboard will surprise you as well. The other touch sensing feature that impressed me a lot is the Chinese characters writing. Imagine that by using a bare finger only and write a Chinese character on top of the screen, the iPhone will recognize what you wrote and give you three other alternative characters for you to choose. The accuracy meets 99%.
As described above, the iPhone 4 is a smartphone but I would like to call it a “Super Gadget”. Why? It is because with the availability of the network connection, the iPhone is a phone, netbook, notebook, electronic book, pocket dictionary, multi-languages’ translator, map, scientific calculator, organizer, engineering tools, portable game console, GPS device, portable media player and much more (you name it, the iPhone 4 got it). For example, it will become my netbook when there is a network connection. It is my map, GPS, compass and multi-languages’ translator when travelling. It is my game console and media player when I get bored. It is my personal Bible which I carry it, and read it everyday and everywhere. It is even my “savior” on my engineering stuff like leveling equipments, engineering unit converter, scientific calculator, engineering formulas and etc. Guess what, I never get bored, lost and never bring along multi gadgets for travelling, and go shopping with my wife. What I need is just to bring along this light and handy iPhone 4
