Can I make an emergency 911 call with an iphone 3gs that has no service?

When a cellular phone indicates that it has "no service," the meaning is that it can't connect to the cell phone tower. It's like having a "land line" phone when someone cuts the phone cord. No matter what kind of cell phone you are talking about, if it indicates on the screen that it has "no service," it can't make or receive calls, to 911 or any other number.
