The next Apple iPhones, to be released sometime in early summer, will likely now be offered in different colors and with different screen sizes. According to Analyst Brian White of Topeka Capital Markets, the “iPhone 5S” will no longer be offered in just black and white, but blue, green, purple, pink, yellow, and silver and slate colors similar to the colors offered when purchasing an iPad Nano.
Additionally, White has mentioned that the iPhone 5S will come in various screen sizes. The iPhone 5 has a 4-inch screen size while the iPhone 4S and iPhone 4 come with a 3.5-inch screen size. What will make these upcoming phones different is that it will be the same model of phone but with different screen sizes, something Apple has never done before. This decision could be due to the increase in popularity of bigger screens.
As of now, these are rumors.
