then you need to backup your sd card, go into cwm recovery, select advanced then partition sd cardHi Hitmax117, I'm looking to use the ext partition as a way of giving myself more room to properly install some of my apps, maybe 500 mb of space so that my big apps can go there and leave the phones internal memory alone.
now what happens next i can't remember exactly but it starts to ask about sizes, always read the top text and only chose 500mb for the first partition(probably it will ask the first partition first), for al the other ones select 0MB
now how to move the apps to ext, you need to activate it, the way to do that depends on the rom you are using, which one are you using?
