I'm posting this here, because I keep needing it and can never remember where I saved it... It's nothing fun to read, just some tech info for me.
1. Set up corporate sync with your gmail account first using the following....
(Username) enter your gmail email
(Email) enter your gmail email
(server) enter m.google.com
2. Accept and save the account.
3. open Settings ~ Accounts ~ and the account you just created.
4. Modify all of the account settings to reflect your actual corporate account.
