A report issued by Topeka Capital Markets on Wednesday morning suggested that Apple (AAPL) has some big changes in store for the next-generation iPhone. According to analyst Brian White, the “iPhone 5S” will be available with two different screen sizes to help Apple better address emerging markets, marking the first time Apple offers a single smartphone model with multiple screen size options. In another first for Apple, White reports that the next iPhone will be available in three new colors — blue, pink and yellow — on top of black and white, which are both currently available. Apple’s most recent iPod touch is available with multiple color options and the new case on the iPhone 5 is aluminum, so it could certainly be anodized — but are consumers interested in different color options for the iPhone?
