Aside from the antenna issue (which I have seen mild evidence of on my phone), my new iphone has dropped the majority of my phone calls. These calls have all taken place where there have been full bars of service, and in areas where I know do not have service issues. One conversation I was having with my friend today dropped 4 times during the 10 minute conversation. Even when I tested out facetime, the call dropped repeatedly. My sister and I both purchased new iphones and recieved them at the same time, but hers works perfectly, even in the same locations where my calls are failing. I'm calling Apple tonight, but I was wondering if anyone was experiencing a similar problem with this???? I did a quick search of the forum to see if anyone else had posted about it, but I couldn't find anything recent.
