Apple has sent an application for registration of a patent to use in making new social network for iPhone users. According to initial information the new social network should be different from the existing general way of functioning. Given that this is merely the patent application is too early to talk about details, but the sight that the whole service should work on the networking of people who are near, but not necessarily know, nor less than necessary to previously exchanged personal information . What you will need to exchange as “tokens”, ie the encryption keys for the identification of managed system. Further details will probably be known soon, and we’ll publish them regularly.
