Apple has posted 2 new banners at the WWDC conference hall Moscon West yesterday, revealing the new Operating systems for mobile device. The company hasn't announced the actual release date of iOs6 but most probably It is just a preparation for the next iPhone.
The fine print on the banner says that iOS6 - is the most advanced mobile operating system in the world. So, claiming something like that makes us feel that we are going to see yet new technologies and improvements in the predecessor version of iOS.
Since Apple will just show it on the iPhone 4S and release the update, but the numerous leaks promise the device - iPhone 5.
