• Choose a Network. Here, you’ll find a list of all nearby Wi-Fi networks
that the iPhone can “see,” complete with a signal-strength indicator and
a padlock icon if a password is required. An Other item lets you access
Wi-Fi networks that are invisible and secret unless you know their names.
See Chapter 6 for details on using Wi-Fi with the iPhone.
• Ask to Join Networks. If this option is On, then whenever you attempt
to get online (to check email or the Web, for example), the iPhone sniffs
around to find a Wi-Fi network. If it finds one you haven’t used before, the
iPhone invites you, with a small dialog box, to hop onto it.
So why would you ever want to turn this feature off? To avoid getting
bombarded with invitations to join Wi-Fi networks, which can happen in
heavily populated areas, and to save battery power.
Fetch New Data
More than ever, the iPhone is a real-time window into the data stream of your
life. Whatever changes are made to your calendar, address book, or email back
on your computer at home (or at the office) can magically show up on your
iPhone, seconds later, even though you’re across the country.
