Extract face will give you what you ask for, but it will be tedious if you have a complex model with a lot of faces.
I am curious why you want the individual faces of the solid model, perhaps if we knew your end goal we could suggest different/faster methods to get what you want.
Actually, in NX 5 we have added an 'Unsew' command which can be used to 'decompose' a solid (or a multi-faced sheet body) into it's individual 'faces', EVEN if the solid (or multi-faced sheet body) was NOT originally created using the 'Sew' command.

In die design, I have to use the inside surface of the part to cut the block for the die and the outside surfaces of the part to cut the block for the punch. For over form flanges I have to rotate the flange surfaces 3 degree and refillet. Sometime to beat the corner with smaller fillet I have to delete the corner fillet and refillet with smaller radius. Thanks for your help.
All of the above will work as well as any command under Edit Surface that allows you to edit a COPY of the surface (Untrim, Enlarge, Isoparametric Trim/Divide and others).
