What if there was an iPhone case that could add three major functions to the device? That is exactly what Charlie Corry set out to do when he came up with the iExpander. He made an iPhone case that adds support for microSD cards, charges your phone and improves the function of the camera’s flash in low light situations. Of course, the iPhone does not recognize the memory as native, so you will have to use their app to copy data back and forth from the phone. Still, this is as close as we have seen to adding more memory to the iPhone in a functional way.
