We all know that when iOS 5 released, Twitter app installed automatically, and there was a developer who tested iOS 5 beta 1 before found that iOS 5 got Twitter app only but also it integrates with Facebook,Flickr and MySpace.
But while mixing with MySpace service the developer found that it doesn’t display all social fields in some examples, and that’s make a question why Apple hasn’t mentioned before that iOS 5 may communicates with services other that Twitter.
Sucking all these contacts up and matching them together to create a sort of Frankenstein social network would not be trivial; Apple would presumably need to match users’ phone numbers, handles, and/or email addresses across various services to disambiguate them.
