Making a call with iPhone is as simple as tapping a name. You won't need to re-enter all your contacts because iPhone syncs with the address book you already use on your computer—Address Book or Entourage on a Mac, or Outlook or Outlook Express on a PC.
If you keep your contacts on the web using Yahoo! Address Book, iPhone can sync with them, too. To get ready for iPhone, organize your contacts in one of these applications and make sure they're up to date with the latest phone numbers and email addresses. If you don't have contacts on your computer, don't worry. You can still enter them directly into iPhone.
Using its built-in calendar, iPhone lets you check your appointments with the flick of a finger. iPhone uses iTunes to sync with the calendar application you already use on your computer—iCal or Entourage on the Mac, or Outlook on a PC—just like it does with your contacts.
If you don't already use one of these applications to manage your appointments, now is a great time to start, so you'll be ready to sync when your iPhone arrives. If you choose not to use a calendar program, that's OK. You'll be able to enter appointments directly into the iPhone calendar.
iPhone is the first phone to come with a desktop-class email application. So now your phone can display rich HTML email with graphics and photos alongside the text. iPhone will even fetch your latest email every time you open the application and automatically retrieve your email on a set schedule, just like a computer does. iPhone works with the most popular email systems—including Yahoo! Mail, Gmail, AOL, and .Mac Mail. If you're not already using one of these services, now would be a great time to get an account. iTunes will make email setup on iPhone a breeze by automatically syncing the settings from email accounts stored in Mail on a Mac or Outlook on a PC.
Don't worry if you're not on one of these email services; iPhone also works with almost any industry-standard POP3 and IMAP email system.
