Just a minor terminology nitpick (I'm about ready to give this one up, but not quite yet): "virtual memory" refers to a a disconnect between logical and physical memory addresses, usually accomplished through dedicated mapping hardware. VM is a prerequisite for things like giving different processes separate address spaces, and also for doing things like memory mapped files. The iPhone definitely has VM. What it doesn't have is swap, which is what you get when you leverage VM to transparently shuffle memory contents between RAM and slower, cheaper storage.
