Do I need to submit updates to USCIS?? thanks

After I submitted 485 in July, I changed to another location in a new
employer. Also, my H1-B is coming to expire when I submitted 485. Do I need to submit my new H1-B and updated information to USCIS Or I just wait to let them ask for REF???

My situation: 7/3/07 submitted 485, H1-B expiration date: end of July

Starting new job at end of July, and got H1-B transferred.


Thanks for your suggestions and experiences.
