We all know the two new iPhones Apple released make great tablets. But how good are they as a phone? Do they feel ok and not too large against your ear as you take calls? Can you use them one handed well (with average or small sized hands)? Is the messaging (sms) app any good? (I only have an iPhone stuck at iOS 3.1.3) Will they fit in small to average sized pockets well? Is their phone antenna as good as previous iPhones? I can't think of any more questions. But thee are the questions I'm really looking for answers for. Any advice here would be very appreciated. I am asking these questions as I have an iPad for all my tablet needs. I want to upgrade my iPhone 1 to a better phone. So that's why I am asking.
