memory-usage

Hello,

I've been staring at the Memory Monitor in Instruments and I am scratching my had. Why is it displaying virtual memory? iPhone OS has no virtual memory. What does it mean?

My concern is that I am getting memory warnings for my iPad app but the apps real memory never exceeds 70MB and the virtual memory never exceeds 180MB?

Could someone please enlighten me?

Cheers,
Doug
