Apple MUST know by know whether it is a hardware or software problem. Their silence on the issue is disturbing. Perhaps they have realised it is indeed a hardware issue so to reduce costs they will WAIT until after the 14 days right for full refund expires. Then they will give you REFURBISHED iPhones NOT new ones - thereby reducing their own costs. This will also deter people with the reception problem from getting an exchange and putting up with a lesser evil - who knows what you may be getting as a refurbished unit. Your views?
