They say it's the little details that make the difference.
Apple has always maintained (obsessively) attention to detail, both in hardware and operating systems.
To the joy of many back an old feature of iOS: the photo in full screen incoming calls.
With iOS7 us "resigned" to have the image of the caller in a small circle in the upper right corner, but it seems that the arrival of iOS will bring eight new photos of our family and friends fullscreen.
Although the function has not been made official, the news of this change "presupposes" an image from the official Apple website, which shows a simulation of an incoming call and the contact photo in big full screen.
Chances are that iOS8 the user can choose which of the two solutions you want to personalize your device.
