case 1 if u r using phone mem to save incoming msgs:
open messaging->settings->other->mem in use-> change to mem card.
it will say to copy the messages to phone chose yes. then it will ask to copy or move the messages chose move, so that msgs will not be on the phone they will be transferred to mem card. then format ur mem card
U R DONE the message will be deleted. now if u want u can switch back to the phone mem if u want

case 2 if u are using mem card to save incoming messages:
its simple just format ur mem card!!
