Assalaamu Alaykum
Many cheeses in the U.S.A. do use rennet. Some even use a pepsin enzyme developed from the stomach of pigs (rendering it Haraam no matter what).
Philadelphia Cream Cheese (and all other cheese under that brand name) doesn't use rennet or that pepsin enzyme. The same is true for Kraft Neufchatel Cheese.

Contact the companies producing Cheese to ask if they could stop using rennet and start using "Microbial Enzymes" (a bacterial enzyme that's not from animal or vegetables. If they use this, then your cheese will be Halal. Be sure to mention the value of your dollar and the 4,000,000 + Muslims' (in the U.S.A) dollars that are at risk!
