So I have been having call issues since I bought my iphone 5 in November. it has a call failed about 50% of the time and have tried many things to no avail. well Verizon has offered me a like new replacement. what is everyones opinion on these? are they in good shape. better than refurbished? reason I am concerned is my iphone is in perfect shape. no marks. battery is okay but nothing great. I get about 7 hrs on a good day. would it be better for me to try contacting Apple? I don't have one close to me to go into. Also they will tell me I don't have phone support so may not get any help. so what would you do?
