Yes. Without two DS' you cannot use the PokeTransfer.
If you have two DS', load up a Generation IV game on one and Go to the Transfer Lab one White. Have the one with the Gen IV game inserted go on DS Download Play, and the other begin the transfer. Load the PokeTransfer panel and choose 6 Pokemon to transfer. Pokemon that know HMs cannot transfer, and items will be left in the Bag. Go to the DS with White in it now, and play the minigame to catch them all. Once done, they will be transferred to White's PC. Voila.
