Hi, my multiboot menu looks like this:

1- Maemo 2.6.28 omap1
2- NITDroid 2.6.28.NIT 07 on mmcblk0p2
3- NITDroid 2.6.28.NIT 06 on mmcblk1p2

i used this
sudo gainroot
mount /dev/mmcblk0p2 /and
cd /and
leafpad ./default.prop

to edit to:
persist.swap.dev=mmcblk1p3
persist.swap.swappiness=1

Is this working now or is there something wrong with the memory card partition? or this: persist.swap.dev=mmcblk0p3?

First of all, it is 2.3.4
Secondly it is N12
Thirdly, all you need to do is change persist.swap.swappiness=0 from 0 to 1
persist.swap.swappiness=1
finally, why did you open a new thread for such a simple question?

Because i have separate default.prop on mmcblk1p2 and mmcblk 0p2 and dont know if it's using the swap correctly.
