Apple has stuck resolutely by its long standing philosophy with its iPhone range hitherto, and the iPhone 5's slightly increased display size is about as radical as it has been thus far. But according to multiple sources of Reuters, the Cupertino company is exploring the possibility pushing display diameters up to 4.7 inches, with suggestions that an iPhone with a 5.7 inch screen is also part of the thought process. Should Apple decide to press on with the project, said devices would manifest themselves at some point next year, and with the same report also hinting at multiple color configurations and $99 starting price points for future iPhones, is Apple about to break away from old habits?
