friends said, iphone 4 has retina, iphone 4s has siri, iphone 5 has nothing new. yes it's only refinements made on the iPhone 5 that makes using it much more pleasure. but iPhone 5 for me has a really best and important feature, it's something we complained al lot when we heard the rumour about iPhone 5 was only going to use the battery almost as the same capacity as the 4S's battery. man this amazes me. info: i dont use LTE, because dont have LTE in my area.
