The iPhone is a marvelous re-imagining of the smartphone. It is evolutionary and revolutionary at the same time. However, it is also very easily broken. It is probably more fragile than most smartphones on the market. One accidental slip from a decent height and it could be game over for your $550-$650 investment. Unlike most cell phones, AT&T does not provide any insurance on this phone, so care for the iPhone is not just a precaution but a necessity.
