I'm logged in to my Gmail account on my iPhone.
On the iPhone I click "+" under Phone \ Contacts, and I add a contact.
I decide I'd like the convenience of using my desktop to add a few more contacts, and I use Gmail to add those contacts.
I see those contacts on the iPhone, but I do not see the contact I added on the iPhone on Gmail.
My best guess is that I have somewhere a setting that makes iPhone contacts sync with Apple, not Google.
How do I see (perhaps on the iPhone) whether a given contact is syncing with Gmail or with Apple?
