Coding with VM limitation on the iPhone?

I'm writing an app for the iPhone, but I need to be mindful how much virtual memory there is available to the app when it runs, so I can manage allocing and deallocing some large arrays. I'm guessing that the OS runs in a small amount (100MB?) of flash memory compared to the 16GB or 32GB of general storage memory? Also, is there a system call I can invoke from within my app to determine how large it is getting?
