DESIGN FIRMS FOR INTERNSHIPS NY TO SF

Well, It’s internship time. I am living in NY and have family in San Francisco, so I would like to try and look for good companies (product design/consumer electronics) in both areas. My Questions are:

What online resources are there for finding good firms ?
Does anyone know of some of the “heavy hitters” they would recommend working for
Does anyone have a firm they have worked for/interned at where they learned a lot?
Any other useful info you might have.

Thanks
