The rumor has already made ​​its way, it's been a while we hear of a  Nano Sim and integration in the new iPhone 5 of Apple , the operators had also ordered large quantities of Nano Sim cards .
For the arrival of such a format sim card on the iPhone 5 , it was necessary to expect a reduction in size for the dedicated compartment and this is what we can see on the picture we are presenting today.
The size difference is pretty minimal indeed, but it would allow Apple to arrange the best parts inside the new iPhone 5 . Hope that the firm takes advantage of this extra space to introduce a better battery capacity!
