Ever heard of accidents? That has nothing to do with caring for your phone. It is purely 'accidental'. The phone may slip out of your hand (the metal band, unlike the rubberized finish of some Android phones is slippery), you may fumble when taking your phone out of your pocket, etc. An Android phone would likely survive the fall with nary a scratch. An iP4 on the other hand may or may not crack (the back glass seems particularly susceptible).
Ehh, not that you'll care. Apple fanbois will be fanbois.
