When a friend was physically moving and needed to retire their Cableone.com account and move to a GMail account, I thought it would be quite easy. After an hour I realized, not so much. Here's the tricky part, Cableone.com mail accounts are already hosted by Google, so the pop account questions asked during GMail import are not what you would expect. In Gmail select "Accounts and Import", then "Import mail and contacts"
Email address is really "firstname.lastname@example.org", the ".net" threw me.
Pop server is "pop.gmail.com"
Port is "995", select "edit" and select "SSL".
