Hello, I have an iPhone 5 for 2 months now and I've been having really bad reception in my house. I don't think is the signal because my wife has another iPhone 3Gs and the reception is good. I took my 5 to an Att store and they changed the sim card in case there was something wrong there... still having bad reception. Every time I want to make a call I have to go outside the house. Just now I was talking and the phone dropped the call and it was showing no service... Would it be something wrong internally?... anyone else had this issue with the iphone 5? Thanks!!!
