Yes, if you have a ton if pics, music, downloads, etc on your internal memory transfer it to micro sd. Stated above "For a rom you need at least 2 gigabytes" is mis leading,(if not referring to total partition size) as you are givn a choice of 1, 2 or 3 gig space. I have never used anything over 1gig, and never ran out if space/memory. Factory reset does not clean your phones storage.. I suggest manually deleting/ formatting for best results to get your space/memory back.
