In the annals of smartphone history, the iPhone 5 holds a cherished place. With its sleek aluminum body and precisely the right screen size for one-handed use, many users consider it a golden-era device.

That particular version of the past is closed forever, its digital door locked and the key thrown away by Apple itself. In the annals of smartphone history, the iPhone
