I am not satisfied with the current iphone 5. The display is too small and its more of the same old. But nevertheless I need a smartphone now. So I want to buy an iphone now and sell it later when the 5" iphone with fingerprint reader is announced. Which iphone would have the best resale value? the iphone4, 4s or 5? I am also assuming that the 16gb loses its value the least compared to 32gb or 64gb.
