Needless to say, the risk of hearing damage exists only when you’re wearing<br />

earbuds. Music pumped through the tiny speaker wouldn’t damage a gnat’s<br />

hearing.<br />

• Video. When you play a video you’ve seen before, you can have it begin<br />

either from Where Left Off or From Beginning. You can also opt to see<br />

dialogue subtitles (Closed Captioning), when available (which is almost<br />

never).<br />

• TV Out. Apple’s $50 TV cables let you play your <strong>iPhone</strong>’s videos on an<br />

actual TV set. You can use these options to control the format of the<br />

video signal the <strong>iPhone</strong> sends: Widescreen (on or off ) or TV Signal (NTSC,<br />

the U.S. video signal, or PAL, the European standard).<br />

Photos<br />

All of the options here govern the behavior of the photo slideshows described<br />

on page 98.<br />

• Play Each Slide For. How long do you want each photo to remain on<br />

the screen? You can choose 2, 3, 5, 10, or 20 seconds. (Hint: 2 is plenty, 3<br />

at most. Anything more than that will bore your audience silly.)<br />

• Transition. These options are visual effects between slides: various<br />

crossfades, wipes, and other transitions.<br />

• Repeat, Shuffle. These options work just as they do for music. Repeat<br />

makes the slideshow loop endlessly; Shuffle plays the slides in random<br />

order.<br />

App Store Preferences<br />

If you’ve indulged yourself by downloading some goodies from the App Store<br />

(Chapter 11), then you may well find some additional listings in Settings. This<br />

is where downloaded programs may install setting screens of their own. For<br />

example, here’s where you can edit your screen name and password for the<br />

AIM chat program, change how many days’ worth of news you want the NY<br />

Times Reader to display, and so on.<br />
