iOS 9.3 is coming in the Spring and will introduce Night Shift as well as a number of other new features.
iOS 7 May Include AirDrop Wireless File Sharing Capabilities
First introduced with OS X Lion, AirDrop is a Finder function that allows Mac users to share files with other Mac users without the need for a Wi-Fi network or storage device. AirDrop for iOS is said to work in the same way, allowing files to be quickly shared between two different users.
Sources say that the AirDrop functionality is currently integrated into the standard iOS share menu. AirDrop will work between two iOS devices and potentially between an iOS device and a Mac. The feature will make it easier than ever to transfer, for example, a photograph or document from one person's iPhone to another person's iPad.Along with AirDrop file sharing, iOS 7 is also expected to feature a major redesign and enhanced social network integration, which includes support for both Flickr and Vimeo. As noted by 9to5Mac, beta features that are in testing, like AirDrop, may or may not make it into the final version of the operating system.
While iCloud synchronization works well for sharing photos and documents between two iOS devices owned by the same person, the AirDrop feature will allow seamless individual file exchanges between iOS devices belonging to different people.
iOS 7 will debut at the keynote of Apple's annual Worldwide Developers Conference, which is scheduled to take place on June 10.
