New 3G IPhone

The iPhone 3G is the second generation of the iPhone line of Internet and multimedia enabled smartphones. Introduced to the world at the WWDC 2008 held at the Moscone Center in San Francisco, the Apple iPhone 3G is very similar to the original iPhone, containing the same 2 MP camera which does not support video recording and which is limited by the same amount of 128 MB of eDRAM memory. However, the first and second generations of iPhones are not the same, the iPhone 3G being equipped with several improvements over the first device such as Assisted GPS, 3G data or Quad-Band UMTS/HSDPA.

Like any other iPhone model, the Apple iPhone 3G runs the iOS (formerly called iPhone OS) operating system,which is based on the Mac OS for Machintosh. Based on the Mac OS for Machintosh means that Apple has incorporated certain parts of the Mac OS in the iOS, like the one which deals with motion graphics. The iPhone 3G can run a large number of applications, as long as they are checked and approved by Apple itself and obtained through their official online web store called the AppStore.



Installing third party applications that do not meet these terms may cause several technical or software malfunctions which cannot be covered by the warranty. This iPhone model control is built around the capacitive Multi-Touch based Liquid Crystal Display (LCD) 3.5 inch screen. This screen was intended for bare finger usage so normal styluses and gloves will not work because they are not able to produce the needed amount of electrical conductivity in order for the device to sense and register your finger and touch gestures.

The 3.5 touch screen runs at a 320x480 (VGA) resolution, with 163 ppi (pixels per inch). The iPhone 3G has a total number of 3 sensors: the repositioned proximity sensor which helps the device figure out when you bring it near your face during a call,and then turns off the touch screen, so no inadverent input would be brought near the user's face and ears. The second sensor is an ambient light sensor which, accordingly to the light in the place where it is located, is able to change the screen's brightness which will save a considerable amount of battery.



The third sensor is the 3-axis accelerometer, which helps the iPhone orient and figure out in what directions it is being moved. This sensor comes in handy for certain applications, or games such as racing, where you turn your iPhone left or right, simulating the movement of a steering wheel, so when your device goes left, the car in the game goes left as well, and then same goes for the right side as well. Even tough they looks somehow alike, iPhone 3G is more complex than iPhone 2G.
