According to the latest rumors about Apple’s upcoming mobile OS, we could be looking at social photo and video integration in iOS 7 by way of Flickr and Vimeo support. Most likely the two services will be added to the existing social sharing options of Twitter and Facebook.
The source of the rumors is a 9to5Mac article which reads:
"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."
This does mean that along with Twitter and Facebook, other third-party apps would be allowed to hook into Flickr and Vimeo by way of an instant log in. However, it’s important to note that not every feature that’s being tested on iOS 7 are to stay after it arrives, so the Flickr And Vimeo integration may both be removed before Apple releases its next mobile OS.
