Apple unveils new iPhone 5 San Francisco - Agencies After months of speculation, Apple announced its newest smartphone, the iPhone 5, as it seeks to thwart growing challenges from rivals like Samsung, Google and Microsoft. In a packed conference hall at the Yerba Buena Centre in San Francisco, Apple marketing chief Phill Schiller called the glass and aluminum smartphone the “most beautiful product ever made bar none,” and also described it as the best engineering that Apple has ever done . The new phone is available for pre-order on Friday in the US, Canada, UK, France, Germany, Australia, Japan, Hong Kong and Singapore, and will ship one week later. By the end of the year it will be available in 100 countries through 240 carrier partners, Schiller said. The new iPhone features a 4-inch (10.16-cm) screen, the largest-ever on an iPhone, which has sported 3.5-inch (8.9-cm) screens since the launch in 2007. While competitors from Samsung, Motorola and HTC offer bigger screens, the “phone has to be designed for the hand. It should fit in your hand, and be easy to send messages, type emails, and surf the web,” Schiller said. Schiller also shared a few other key statistics about the phone, which at 7.6 mm thick is the world’s thinnest smartphone, 18 per cent thinner than its predecessor. The iPhone 5 weighs 112 grams, 20 per cent lighter than 4S. The phone runs on Apple A6 chip which is twice as fast and powerful as the A5 chip used in the previous version of the phone. It will access the latest LTE cellular networks and feature a battery that’s good for 10 hours of web browsing over Wi-fi, dpa reported. The camera is built around an 8-megapixel sensor and features a precision five-element lens for better low light performance and 40- per-cent faster photo capture. Apple also improved video capture and the phone’s audio system, including a noise-cancelling earpiece, Schiller said.
