How does my HTC EVO™ 3D back up and restore contacts with Gmail™?
If you sign into a Google™ account during the initial setup process, your HTC EVO 3D automatically synchronizes contacts with your Gmail account.
If you add contacts to your HTC EVO 3D before signing into your Google account, your contacts don't synchronize with Gmail. They save as Phone Only contacts.
After you've associated your Google account with your HTC EVO 3D, anytime you add, import, or transfer a contact, your device prompts you to choose where to save the contact. Contacts don't synchronize with your Google account unless you select Google Account.
