I would like to know your opinions as to which was the best and worst iPhone. I have not much knowledge as the previous iPhone 4, but I think that the best has been the iPhone 4S. In addition to better speed than its predecessor, incorporates Siri, panoramic photos, 8mp (which until today still in the iPhone 5S), a dual core ... And I would say the worst was the iPhone 5, although a great phone, not innovate beyond the upgrade in speed and increase the size of the screen. For me it is like an iPhone 4S but bigger and faster. I hope their views
