WP7 - storing a couple of values....

I've a Windows Phone 7 application. I want to store a couple of values to the phone so that I can retrieve them later. These are basically configuration settings:

boolean field1 = true;
boolean field2 = true;
boolean field3 = true;

The user can change these to false if they want. I want to store those values so that the next time the phone app loads, it is the users settings.

What would be the easiest way to do this? Anyone have a simple code example for me to pull from?

Thanks,

Brad!
