Sync Contacts From iPhone to Gmail
The first thing you need to do is set up your gmail account as an Exchange account. I don't know if the contact syncing method works as a Gmail set up. The Exchange method is superior anyway. Also, if you have an exchange account, you can skip down to where I say "First, click on the Contacts icon" a few paragraphs below.
To set up your gmail as an Exchange account, go to "Settings" then "Mail, Contacts, Calendars" click on your gmail account and then click "Delete Account" at the bottom. Don't worry, you won't lose your emails. Then go back to the "Mail, Contacts, Calendars" and click "Add Account". Then select exchange and put info in this format -- note that this is what it looks like after it's set up:
You won't see a "Server" box until you fill out the first screen.
Leave the "Domain" blank and make sure you put in your full email address. The description can be whatever you want but it's probably best to call it "Gmail". When you do enter your info and the "Server" box pops up, put in m.Google.com like I have in the screenshot above.
Now you need to make sure that at least your Mail and Contacts are set up to sync. You don't have to do Calendar but I suggest it as well. Here's a screenshot:
Okay, now you're set up to do this whole thing properly. Moving onâ¦
First, click on the Contacts icon. In case you're confused about what I'm talking about, I'm referring to this one:
Once you click on that, you should see something like this pop up. The difference is that it might not say just "Contacts" at the top. If you're seeing "All Contacts" that might be a problem. We'll fix that now. Granted, you might not know as many famous people as I do (obv brag) but you should see a list of people in 99% of cases.
Here's where you need to do some exploring. Click on the "All from My Mac" option (this may say something different if you have a PC, I'm not sure). If you see anything listed, you're doing it wrong. It should look like this:
Why? Basically anything here is being synced through your mac. It's not being sync'ed through Gmail. Syncing through your mac technically works but it's not as nice as being able to edit your iPhone contacts directly through the Gmail web interface. Now get to work deleting all of your contacts listed in "All from My Mac" and putting them into your Gmail account. The nice thing is that you can do the data entry via the "Contacts" screen in Gmail. Just make sure that you put the contacts into the "My Contacts" group if they don't exist already. There are fancier/quicker ways to do this but for the purposes of this tutorial, just find a way to get the contacts out of "All from My Mac" and into your gmail "My Contacts" group. Make sure your "All from My Mac" screen is empty like the screenshot above.
Now go back to the "Groups" screen and select "Contacts" under the "Gmail" header (ie, the one with the big green checkmark). You should see all of your "My Contacts" group from your gmail contacts listed there. When you make changes, they will sync to your gmail account.
When you make changes to a contact on the gmail web interface, they will sync on your iPhone. Whenever you're in your contacts screen on your iPhone, just make sure you're looking at the right list. If you're not sure, go back to Groups and then select Contacts under Gmail to make sure. Only initiate new contacts via the + button on the correct list -- otherwise they will save to your iPhone only and they won't sync to gmail.
And most importantly, if you lose your phone, it's just a matter of setting up your gmail account as an Exchange account again and all of your mail, contacts and so on will show up on your phone shortly. No need to broadcast your noob status on Facebook ever again.
If you didn't understand this tutorial, you can also read the official Google tutorial to do the same thing. They also have tutorials for other devices.
