The old H1 visa is of no use to you. When you quit working for your first sponsor without transferring your H1 to another employer, your H1 status ended. Your new employer will have to apply for a new H1. Te only importance of your previous H1B is that the time you were in the U.S. in H1B status will be counted against the 6-years limit on these visas.
