Interpret the Sad Face
When you??™re in a bad mood, you probably flash a
sad face. Your iPod does the same (see Figure 2-6).
Its sad face usually appears when there is some
sort of hardware issue. For instance, you might
see the sad face after you drop your iPod, throw it
at someone, or handle it too roughly.
