swapon /dev/block/mmcblk0p3 -----------------to turn it on, the 0 in 0p3 is a zero.
swapoff /dev/block/mmcblk0p3 -----------------to turn it off, the 0 in 0p3 is a zero

you can check your free memory status by typing free after superuser access as well. It will provide total used memoryand free memory for both phone mem ory and swap file (if used)
