i have a question about the partition sd card function of rom manager. which i click on it it says it will take 512 mgs for ext size and swap size 256mg. what does this mean to me? does it help to do this? cus right now i have CM7 install all programs to external storage anyway is there a difference formatting the card like this? does it add it to internal storage? im just curious about this cus it seems interesting if it helps in anyway.
