In the upcoming overhaul of its iPhone, iPad, and iPod touch operating system, iOS 7, Apple plans to include an increased presence of third-party social networks, including Flickr and Vimeo, according to a person familiar with the software. Since the new software is yet to be even officially announced, there is a very real possibility that any feature in testing could be removed prior to the announcement, this person said (much like Facebook integration was removed from iOS 4). Last year, Apple added Facebook integration to iOS, and in 2011, the company struck a deal to integrate Twitter. Both Flickr and Vimeo will now also be integrated deeply into the new operating system, so users will be able to sign into the respective networks via iOS 7’s built-in Settings application. Like with iOS’s Facebook and Twitter ties, Apple customers will be able to log-in one time into each social network and have full sharing access.
