How many phone numbers do you know by heart anymore? I think I’ve got about two committed to memory, not counting my own or 9-1-1. My iPhone, on the other hand, is stuffed with phone numbers, street addresses, email addresses, alternate emails, notes, companies, birthdays and phonetic pronunciations of first names. If you sync your iPhone to a cloud service like MobileMe or Google, you might have an email address for almost everyone with whom you’ve ever exchanged a message.
