I have a google business account (means firstname.lastname@example.org) and all worked great, until I changed the login password.
Now it won't login and it seems the account is not recognized anymore as a Google account.
I'm using the free version (not exists anymore) of google apps for business [users<10]
Tried with Pre3 and Touchpad, same problem.
Right now I'm using the exchange method to sync google calendar, contacts, and services, but no the email (that I'm using by IMAP common service) due is not syncronized well through exchange.
Would be possible that Google has stopped this auto-recognize method for all devices, due now is not free anymore?
