"What else can we use for this?" Yes, this is the most frequently asked question while buying any equipment these days. What we are looking for is that, apart from the "obvious" use, what other equipment is provided. And that's what iPhones are all about. The iPhone is not just a phone but a lot more. Three devices – a combination of mobile phones, ipods and Internet devices.
Apple Inc. designed and distributed iPhones for the first time in the United States on June 29, 2007. Since then, there are two additional versions of iPhones – iPhone 3G and iPhone 3GS. These are other developed versions with the exception of the first generation iPhone. The iPhone 3G supports 3G data rates up to 3.6 Mbps where iPhone 3GS supports faster 3G data rates up to 7.2 Mbps. Google and Yahoo! you can use the built-in search and iPhone multitasking while sending an e-mail or browsing the Internet over a Wi-Fi or 3G connection
Do not forget to press hard on the keyboard buttons on iPhone when dialing any number. The iPhones have multiple touch-screen interfaces that you can easily call a name or number in your contacts list or favorites list, in your call log or from anywhere. IPhones have a 9cm (3.5 in) liquid crystal display (320×480 px 6.3p / mm, 160ppi, HVGA), scratch-resistant glass and 18bit (262,144 colors). The touch screen is designed to perform functions only by touching the bare finger on the screen. Multiple fingerprints can be used for multiple senses. The iPhone 3GS version also includes an oleo-phob coating on the screen that prevents fingerprints from being displayed on the screen.
The iPhone display responds to three sensor proximity sensors, ambient light sensors, and accelerometer sensors. The proximity sensor turns off the touch screen functions during a call. This shutdown prevents unnecessary inputs from your face and ear when you are in a call. The ambient light sensor adjusts the brightness of the display, depending on the ambient conditions, while using the accelerometer to switch between portrait mode and landscape
For text input, iPhone provides a virtual keyboard on the touchscreen that automatically checks and corrects spelling, predicting words, and dynamic dictionary that learns new words. The first-generation iPhone did not have GPS hardware where the iPhone 3G and 3GS versions use a supported GPS. The iPhone 3GS also includes a digital compass.
The iPhone and iPhone3g's built-in 2.0 megapixel camera with optical zoom, flash and autofocus. It does not support video recording. The iPhone 3GS, however, has a 3.2 megapixel camera with autofocus, automatic white balance. Can capture 640×480 (VGA resolution) video at 30 frames per second. You can then switch the video to your device and upload it directly to YouTube, Mobile Me, or other services.
The original first-generation iPhone contains 4 GB and 8 GB of internal memory. However, later, the 4GB version was discarded. The iPhone3G is currently available at 8GB and 16GB, while the iPhone 3GS is available in 16GB and 32GB versions.
All three versions of iPhones are accompanied by a USB power supply or a wall charger. The original first-generation iPhone is also equipped with a cleansing cloth, a stereo headset and a plastic dock that holds the phone vertically while charging. The 3G version has a similar headset and includes a sim separator. While the 3GS version has a SIM release tool and a headset with a volume control switch.
The iPhone opens a completely new application world. You can choose thousands of apps and download them with a touch. For all applications, the iPhone is going better. Be more effective. Have fun. Play games, contact your friends on the face book, or discover new restaurants with the city spoon. No matter what you want to do on the iPhone, there is an application for that. If you buy an iPhone, you will not buy a mobile phone, but you will build a whole new world around you.
