From Lifehacker: The iPhone is a fantastic phone, but if you're a heavy user of Google services, it can be a little confusing to set up your Gmail, Google Calendar, and Google Contacts to sync with iOS. If you follow the directions on iPhone and set up your Gmail the way they say, you'll get your mail, but your gmail contacts won't be synchronized with your phone. But if you choose Microsoft Exchange at the prompt instead of Gmail, this will give you access not only to your Gmail, but your calendars and contacts, and they will all sync directly to your phone—when you add a contact in Gmail or edit an event on Google Calendar, you'll see it show up on your phone without having to sync anything. Here's how to set it up.
