Question [Q] (Q) Help switching back sdcart-ext with sdcard

I did the partitions swap right when this phone came out, which tricked my phone into thinking my external sdcard was in fact internal memory.

I would like to switch this back. Does someone know of a simple way to do this? I believe it requires a void file or something - I'm not sure. I am sure that I didn't make a backup of the original file when I overwrite the new one. Dumb.

Someone help this guy out please. I get all sorts of confused when my phone says it can move and apps to the sdcard. I have no idea where it goes. Now I'm getting a "sd card low on volume space" alert constantly. Pulled up Apps2sd and it wont even let me move anything anymore.

I would love to avoid an SBF.

Thanks.
