Steve Jobs replied back on iPhone 4 antenna and reception problem. He suggested a new way of holding the phone while talking. Of course it is not accepted by customers as they want to hold it anyway and that’s what Nokia told them about their phones. Here is the Steve showing proper way of holding Apple iPhone 4. It is other story that Steve also hold phone in normal way while showing off it in WWDC 2010.
But Steve there is one more way thru which people will not face reception problem while talking. As antenna of iPhone 4 is nothing but the outer body of the phone and when user will hold that, antenna will not get proper signal. So probably a hardware support like below will work.
So this is iPhone 4 with old fashioned telephone.
