I am on my 3rd replaced Iphone and I am counting down the days to the end of my contract. It drops calls daily, I have had an issue where my phone completely locked up. I took it to the apple store and they described the problem as a “complete hardware failure”. When I update my OS it kills some of my apps. I visited NYC and was in Manhattan and could not get a signal. The GPS is a joke in NYC. It was off on my location by several blocks.Overall: this phone sucks @$$.
