About IPhone in brief
The iPhone is a line of smartphones designed and marketed by Apple Inc. that use Apple’s iOS mobile operating system. The first-generation iPhone was announced by former Apple CEO Steve Jobs on January 9, 2007. Since then Apple has annually released new iPhone models and iOS updates. As of November 1, 2018, more than 2.2 billion iPhones had been sold. The iPhone has a user interface built around a multi-touch screen. It connects to cellular networks or Wi-Fi, and can make calls, browse the web, take pictures, play music and send and receive emails and text messages. Since the iPhone’s launch further features have been added, including larger screen sizes, shooting video, waterproofing, the ability to install third-party mobile apps through an app store, and many accessibility features. Up to 2017, iPhones used a layout with a single button on the front panel that returns the user to the home screen. Since 2017, more expensive iPhone models have switched to a nearly bezel-less front screen design with app switching activated by gesture recognition. Apple created the device during a secretive collaboration with Cingular Wireless at the time—at an estimated development cost of US$150 million over thirty months. According to Steve Jobs, the \”i\” word in \”iMac\” stands for internet, individual, instruct, inform, and inspire. Apple rejected the \”design by committee\” approach that had yielded the Motorola ROKR E1, a largely unsuccessful collaboration with Motorola.
Apple is one of the two largest smartphone platforms in the world alongside Android, forming a large part of the luxury market. It has generated large profits for Apple, making it one of the world’s most valuable publicly traded companies. The original iPhone was made of aluminum with a black plastic back with a full plastic accent. Many would-be users objected to the iPhone 40% of the cost over US$100, and the original iPhone 3G and 3GS feature a full Plastic back to increase the strength of the GSM signal. The 4GB iPhone 4 has an aluminosilicate glass front and a stainless steel back that serves as the front edge that serves the antennas. It was not available in white until the first black version was released in April 2014. It is available in both colors, regardless of the storage capacity, and regardless of whether it is a GSM or CDMA model. The 3GS was available in an 8 GB black or a white option for the 16 GB model, but not a white or a 16GB black model for the iPhone 3GS. Apple has not released the iPhone 4S or 4S in white or white, but it was not announced in April 2013. It will be released in both white and black, but the white version was not released until April 2014, but a white version for the 4GB model was not offered for the 8GB model. Apple’s App Store contained more than two million applications for theiPhone.
