iPhone THE MISSING MANUAL - Cdn.oreilly.com

Multitasking
Don’t forget, by the way, that the iPhone is a multitasking master. Once you’re
on the phone, you can dive into any other program—to check your calendar,
for example—without interrupting the call.
If you’re connected to the Internet via a Wi-Fi hot spot (page 106), you can
even surf the Web, check your email, or use other Internet functions of the
iPhone without interrupting your call. (If you’re not in a hot spot, you won’t be
able to get online until the call is complete.)
Silencing the Ring
Sometimes, you need a moment before you can answer the call; maybe you
need to exit a meeting or put in the earbuds, for example. In that case, you
can stop the ringing and vibrating by pressing one of the physical buttons on
the edges (Sleep/Wake button or either volume key). The caller still hears the
phone ringing, and you can still answer it within the first four rings, but at least
the sound won’t be annoying those around you.
(This assumes, of course, that you haven’t just flipped the ring-silencing switch,
as described on page 12.)
Not Answering Calls
And what if you’re listening to a really good song, or you see that the call
comes from someone you really don’t want to deal with right now?
