You typically only get about 5-40MB of available RAM. Its not flash.
Its real RAM. But you have no guarantees. The iPhone has a robust
memory system with low memory warnings and such and you just have to
use those to determine if you have enough.

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?
