I understand that prime upgrade pricing depends on whether I have a gmail or a gapp account. Presumably, gmail accounts are for individuals and are non-commercial, while gapp accounts tend to be commercial.
I have an individual Google account which used to have an associated gmail address, but I cancelled my gmail service some time ago. My email address for the Google account is of the form user@host.com. I am not a commercial user, and I am not using Google Apps.
So can I be a gmail account for purposes of upgrading?
