Over the past several months, there have been several rumors suggesting that a move to two different screen sizes on the iPhone 6 could come with a $100 price premium for the larger model. Rumors have indicated that Apple is planning to launch a 4.7-inch iPhone 6 around the September time frame, with an even larger 5.5-inch model coming either at the same time or up to several months later. Raymond James analyst Tavis McCourt has now weighed in with his own belief that the larger model will indeed include a $100 price premium. But according to McCourt’s survey data, consumers are showing an increasing willingness to pay that premium for a larger device.
