Two days ahead of the launch of the Apple iPhone 5s and 5c, the iOS 7 upgrade has been made available for download. Users can look forward to an entirely new look and feel, highlighted by revamped icons, typefaces and other visual elements. Stock apps like Safari, Calendar, Camera, Mail, and Messages have been upgraded, and there's a newly installed Control Center, through which you can adjust commonly used settings without having to launch the Settings folder. Some of the major new features users can look forward to include AirDrop, a peer-to-peer file-sharing service; iTunes Radio, Apple's new streaming music service; a revamped Siri that uses data sources like Bing, Wikipedia and Twitter; and less restricted Multitasking that adds a whole new user interface for switching between apps. Representing the first major redesign of the OS since the original iPhone, iOS 7 is available for free download now.
