You don't technically
need to do to it, but in order to gain more app space you should understand exactly
how your memory is being used in the first place.
Apps2sd is already enabled in the ROM by default as stated in the ROM OP. You do not need to do anything extra. Like I said, keep apps on internal and your apps and dalvik cache will be moved to /sd-ext, you should be able to check this now with DiskUsage.
I recommend starting
here for fastboot guide, that's the only thing you're missing. Flashing things through fastboot isn't that hard once you get used to it, and can be crucial in certain situations. Once you flash the ROM on cm7r2 hboot, you'll be using your space more efficiently and have a lot more space for apps.
I know 287MB doesn't seem like much more. But this is /data partition is only used for app data. This will still get filled up as you install apps, but much more slowly :good: The apps and dalvik cache which take up much more space go to sd-ext, which is what you want.
You can refer to the same videos if you really want to see 1.5GB internal memory, they likely use a 'data2sd' or equivalent script but in my experience it's not worth it. You would have to remove the current working script, and replace it with something else, which is risky if it's incompatible and untested. Even if you do this, you're not actually gaining anything extra. You have already created the sd-ext partition; it's size is whatever size you set it when you partitioned. It does not change depending on the A2SD script.
I understand that having a 'visible' 1.5GB memory looks better...but once you realise your partition is already there and being used correctly, you don't
need to see it.
